Leery of coughing up $200 or even $300 for yet another iPhone? Well, you can always sell your old iPhone on eBay. But there’s another, potentially easier option: trading it in for cash. Some online trade-in sites offer up to $320 for iPhone hand-me-downs.
I checked out iPhone trade-in values at five of the most popular online gadget trade-in sites — Cell for Cash, FlipSwap, Gazelle, NextWorth and YouRenew — and found some pretty decent offers for all the previous (locked) iPhone models. In some cases the money would be enough to completely offset the cost of a new iPhone 4.
Of course, the price you’ll get for your old iPhone depends on the condition it’s in (mint? almost new? a little scuffed? cracked screen?) and whether you have the original accessories (namely the headset, the connector cable and the power adapter). Oh, and if your iPhone has suffered any water damage or doesn’t quite turn on anymore, well … good luck with that. Make sure to check with the trade-in site you pick to see what their policies are for phones that fall short of their wear-and-tear expectations: In some cases, a given service may not notify you if it lowers its offer for your phone, or won’t give you the option of getting your phone back if you disagree with a lowered offer.
Even if your old iPhone is in mint condition, you’ll have to be patient. Most trade-in sites will take days or weeks to cut you a check once they receive your old handset in the mail. Typically you send in your phone yourself. Some sites will send you a box for shipping, but then you’ll extend your wait even further.
I checked the iPhone offers on each of the five sites, using the assumption that iPhones were in “good” shape (between “mint” and “fair” condition) when I had the choice. I also checked the “have cables and power adapters” box where applicable. Also, keep in mind that the prices I’m quoting here are subject to change daily (usually ever lower as time marches on).
The results: Across the five sites, a 32GB iPhone 3GS fetched an average of $274, just $26 less than the $299 two-year contract price for a new 32GB iPhone 4. Cell for Cash offered the highest price — $320 — but the site doesn’t give you the option of indicating what shape your iPhone’s in, so it’s quite possible that an even gently used iPhone might get you less than that.
The average offer for a 16GB iPhone 3GS, meanwhile, was about $228.
What about the iPhone 3G from 2008? For the 16GB model, expect an offer in the vicinity of $150 (the highest offer, $186, again comes from Cell for Cash); the 8GB iPhone 3G might get you about $134, depending on the specific trade-in site.
Even the original iPhone will score you some cash: The 16GB version fetches an average of just over $100 (FlipSwap being the most generous at $114), and the 8GB iPhone yields a decent $81 average. Last but not least, the 4GB version will rake in an OK trade-in value of $67 or so (highest offer: $78, from YouRenew).
Wondering why you can (in some cases) trade in your phone for more than you paid for it? Well, keep in mind that the $299 price you paid for your iPhone 3GS last year was subsidized by AT&T, which recoups the cost through your monthly cell phone bill. The unsubsidized value of your phone is much higher — $699 in the case of the 32GB iPhone 3GS. Trade-in sites typically sell the working phones they receive to wireless resellers, which refurbish the used phones and put them back on the market. They may also strip a handset down and sell off its parts — or, in the case of a phone that’s truly busted, divert it to a recycling program.
Oh, and one more thing: Be sure to wipe all your personal data off your iPhone before you trade it in. Most trade-in sites promise that they’ll wipe your handset for you — but better safe than sorry. (To completely wipe your iPhone, tap “Settings” and then “Reset,” then select “Erase All Content and Settings.”)

A Gold Master release of iOS 4 (née iPhone OS) was seeded to developers yesterday. And the next iPhone’s software has been surprisingly accommodating to jailbreakers’ attempts to crack it wide open.
iPhone 3GS 4.0 GM Jailbreak
The current technique was finagled from existing jailbreak software (Pwnagetool, specifically) by msft.guy. On top of this prerelease hack, the iPhone Dev Team is claiming to have an unlock of their own nearly prepped for iOS 4 final, to be released within a month (presumably to coincide with the release of iPhone 4). In other words, come iOS 4’s official release, you should be able to jailbreak your handset—or at least your iPhone 3GS. (Nobody’s been able to test the exploit on an iPhone 4.
Instructions for trying the current jailbreak, for 3GS only, are available here, but it’s probably a bad choice: The final release of the software is set for the end of this month, at which point the jailbreaking process will likely be streamlined (and anointed by the Dev Team), and after which your jailbreak will last longer than a few weeks.

Apple has posted the QuickTime stream for Monday’s keynote address for WWDC 2010.

The keynote has also been added to Apple’s podcast feed.

Apple announced a number of items including:
- Apple’s iAds Going Live on July 1
- iBooks Update to Include Notes, PDF Compatibility
- iPhone OS 4 Becomes iOS 4, Available June 21 for Free
- Apple Announces iMovie for iPhone 4
- Apple Announces FaceTime for iPhone 4 Video Calls
- Apple Announces iPhone 4 with Retina Display, HD Video Recording

With AT&T’s announcement today that it is rolling out new data plans next week for the iPhone and other smart phones, many customers have been thinking about which data plan is right for them in light of the new download limits.
AT&T iPhone customers can view their data usage for the current billing period on the summary page for their account by logging in to the AT&T Wireless website. Such data is only an estimate, however, and AT&T notes that delays of up to five business days may be experienced before data activity shows up in the displayed total. Users can also dial *DATA# and receive a text message with their current billing period’s usage.
From their AT&T Wireless account summary page, users can also click on the “View Past Data Usage” link to see a six-month history of their data usage to help gauge which new data plan they may want to select.
For existing customers who wish to keep their $30/month unlimited data plan, they can continue on the plan even if they upgrade to new hardware. If a customer elects to switch to one of the new plans, however, they will be unable to switch back to the unlimited plan at any point in the future. Customers on the grandfathered unlimited plan will also be unable to use AT&T’s tethering feature, which comes as a $20/month add-on to the new $25/month 2 GB data plan.

AT&T’s announcement of their new capped data plans has generated a lot of discussion amongst current and future iPhone owners. In short, AT&T eliminated their $30/month unlimited plan for new iPhone customers starting on June 7th. After that time, new iPhone (and other smartphone) customers have the option of $15/mo (200MB) and $25/mo (2GB) data plans. AT&T, however, has grandfathered in existing iPhone customers by allowing them to keep the $30/month unlimited plan if they desire.
But with the new iPhone just around the corner, several readers wondered if that guarantee would hold even if they chose to upgrade to the new iPhone. It seems like it will.
AT&T has replied on their Facebook page indicating that current customers may keep the $30/month unlimited plan even when they upgrade to a new iPhone:
The good news for current customers who love their unlimited plan is this: they are not required to switch, even when it’s time to upgrade to a new phone. So you are welcome to keep your unlimited plan
Of course, by staying on the unlimited plan, customers won’t be able to add on tethering service.

Computerworld — Wal-Mart (WMT) today dropped the price of Apple’s (AAPL) 16GB iPhone 3GS by $100 to $97, according to the retailer’s Web site.
Multiple reports, including from the Associated Press and the Wall Street Journal , had said that the giant retailer’s new price would go into effect Tuesday and run indefinitely. As with all iPhones, customers buying the lower-priced 3GS must commit to a two-year contract with AT&T.
iPhone OS 4.0: Ten Pressing Questions
Slideshow: Forget iPhone 3G S: Eight Great New iPhone Alternatives
Wal-Mart’s Web site listed the new price on the site at 6 a.m. Eastern time today. At 2 a.m. EDT Tuesday, the site had still posted the 16GB iPhone 3GS at $197, a $2 savings over Apple’s and AT&T’s $199.
Wal-Mart was not available for comment late Monday.
The move will likely be seen as the best evidence yet that Apple CEO Steve Jobs will unveil the next iPhone June 7, the opening day of the company’s annual Worldwide Developers Conference (WWDC).
It’s unknown when Apple would start selling the next-generation iPhone. However, if it sticks to last year’s timetable, Apple will launch its newest iPhone Friday, June 18.
Although Wal-Mart’s timing may be unexpected, the price cut is not: When Apple introduced the iPhone 3GS in early June 2009, it immediately slashed the price of the previous model, the entry-level 8GB iPhone 3G, to $99. Apple and AT&T continue to sell the iPhone 3G at that price.
Most analysts expect that Apple will repeat the move this year: When it unveils the new smartphone, Apple will drop the price of the iPhone 3GS to $99. If so, Wal-Mart would retain its current $2 price advantage over Apple and AT&T.
Rumors that bolstered that speculation hit several Apple and technology blogs earlier Monday. The Boy Genius Report , for example, claimed that its sources said Apple had stopped shipping the 8GB iPhone 3G to AT&T stores, and that further production orders for the 2008-era smartphone would not be placed.
The disappearance of the iPhone 3G makes sense, not only because it makes way for a cut-rate iPhone 3GS, but also because the older model is not able to multitask , the flashiest new feature in iPhone OS 4, the mobile operating system upgrade that Apple previewed last March and promised to release this summer.

You’ve worn the glasses. Seen the demos. Winced at objects flying out the screen. And you’re ready to buy a 3D TV.
Congratulations, brave early adopter. Although the 3D TV maelstrom at CES 2010 generated a fair bit of skepticism, the technology also managed to floor many people, and if the commercial success of Avatar is any indication, 3D movies aren’t going to disappear any time soon. Ready to get in on the ground floor? Watch out, it’s still under construction. But our 3D TV buyer’s guide can help show you how to set up shop in three dimensions. Follow along as we lay your questions on the new format to rest.
Which new models were announced at CES 2010? When will they be available?
Just about every major manufacturer announced a 3D television at CES 2010. Here’s a rundown on the big models in order of their release:
•Panasonic Viera VT25 Series Plasma (Available now)
•Samsung LED8000 Series LCD (Available now)
•LG LX9500 Series LCD (Available in Korea, coming to U.S. in May)
•Sony LX900 Series LCD (Summer 2010)
•Vizio XVT Pro Series LCD (Available in August 2010)
•Toshiba Cell TV ZX900 Series LCD (Fall 2010)
With the exception of Samsung’s LED8000 series (which will be trumped by the LED9000 later on), these represent flagship models. Most manufacturers are also offering more stripped down versions at lower price points. Check out 3DMovieList for a comprehensive list of models, release dates and features.
Can I watch 2D video on a 3D TV?
Absolutely. All of the upcoming 3D TV models above represent flagship models from their respective manufacturers, which means they won’t just play 2D television, it should look top notch. Nothing about the tech needed to make 3D-capable sacrifices 2D images quality, so even if you intend to watch 99-percent of your programming without glasses, you shouldn’t think twice about buying a 3D TV.
Will I absolutely need 3D glasses? How do they work? How much will extra pairs cost?
Every consumer-grade 3D TV today requires glasses to produce a 3D effect. Although many companies have demonstrated tech demos at trade shows that show how 3D can be produced without glasses, none of them are yet ready for prime time.
Unlike movie theaters, which use polarized glasses, 3D TVs use active-shutter LCD glasses. This means a tiny transmitter inside actually communicates with the TV to block your left eye when an image for the right eye is on the screen, and vice versa, 120 times per second. This rapid-fire trickery requires electronics and a small battery, making them heavier and bulkier than the cheap polarized glasses you may have used in a 3D cinema.
Although most 3D TVs will come with one or more pairs of glasses, you should also be prepared to buy additional pairs unless you really plan on sitting in your basement watching Cloudy with a Chance of Meatballs all by yourself. Although not all manufacturers have announced pricing for the glasses that will pair with the new models, don’t expect them to be cheap. Samsung, which already has 3D displays on the market, charges $130 for a pair of its rather dorky 3D shades. Nvidia charges $149. Even if the TV you buy comes with a two pairs, that’s another $260 to get the kids on board, and more if you want to invite the neighbors over to gloat. Make sure to factor the price into your purchase.
What will I be able to watch in 3D?
To be frank, not that much, right off the bat. Although standards for generating and distributing video in 3D have expanded, the market is still pretty slim at the moment.
Your best bet for the time being lies in 3D Blu-ray movies. Manufacturers only recently ratified a 3D standard for Blu-ray, but a few titles are already available. Samsung throws a 3D copy of Monsters vs. Aliens in its Blu-ray starter kit, and Panasonic recently sweetened the deal for its buyers with Ice Age: Dawn of the Dinosaurs and Coraline in 3D with the purchase of any Panasonic 3D TV.
Some TVs, such as Toshiba’s ZX900 Cell TVs and Samsung’s LED9000, will actually be able to generate 3D content from 2D content as well. Although the artificial 3D effect from this method clearly won’t look as good as native 3D (in our demo at CES, it looked a bit like cutouts from a pop-up book, and the rendering tech causes some people to have halos around them), we still think it will be an extremely useful feature while 3D remains immature, and content scarce.
Television stations will start to offer 3D content soon, too. DirecTV will fire up three 3D stations in 2010, ESPN will broadcast select games in 3D, and Sony and IMAX are slated to start their own 3D nature channel. Unfortunately, many of the specifics remain quite vague now, so you may be better off waiting for more information before committing to any one provider.
Do I need a special Blu-ray player for those 3D Blu-ray discs?
Unfortunately, yes. The same companies pushing 3D TVs have committed to producing 3D-capable Blu-ray players this year as well. Here’s a quick list:
•Panasonic DMP-BDT350 / BDT300
•Samsung BD-C3900 / C6900
•Sony BDP-S770 / S470
•Toshiba BDX3000
•LG BD580
So far, it doesn’t look like any previous Blu-ray players will be upgradable, except Sony’s PlayStation 3, which should get a firmware update to make it happen this summer, along with stereoscopic gaming.
What is HDMI 1.4?
At the moment, a certified HMDI 1.4 cable is the only way to carry a 3D signal. That means that your existing HDMI 1.3 cables (which have been the standard since 2006) won’t do the job. A new cable isn’t much of an upgrade investment, but keep in mind that other HDMI accessories won’t work, either, including A/V receivers. If you plan to pass your video signal through a receiver with HDMI, Sony’s STR-DN1010 is currently the only model that will fit your needs.
How big of a screen do I need?
You may recall from our HDTV buyer’s guide that we dismissed the caveman “bigger is better” mentality when it comes to TVs, favoring one that fits the room instead. Well, grow out your unibrow and grab yourself a club, because the reverse is true with 3D. Let’s state this bluntly: You need a big TV to appreciate 3D. Immersion is the name of the game, and the more the screen fills your field of view, the more you feel like you’re “there.” Fortunately, TV manufacturers seem to realize this as well, since we haven’t seen a single 3D set under 42 inches. If you have the extra money to throw at a luxury like 3D TV, make sure to go all the way and buy the largest screen you can reasonably afford or fit in a room, because it will drastically affect your 3D experience.

Owners of iPhones know that their love for Steve Jobs’s touch-screen marvel comes at a price. The iPhone’s cellular coverage, provided exclusively by AT&T Wireless (NYSE: T – News), is notoriously spotty. In some parts of New York and San Francisco, it’s impossible to connect.
If you go for a dim sum lunch at Yank Sing restaurant on the edge of the financial district in San Francisco, you are likely to miss calls from the office. Some owners can’t use their iPhones in their own homes. Even AT&T Park, the city’s waterfront stadium, can be a dead zone.
The iPhone service is affected by several factors. First, AT&T’s 3G network doesn’t cover as much ground as Verizon (NYSE: VZ – News), America’s largest carrier. Second, urban areas packed with tall buildings are bad for wireless signals. Skyscrapers can block radio waves, or they can bounce them around to create what’s called multipath interference, where signals from different directions collide and cancel each other out.
But the iPhone’s worst enemy is the iPhone itself. So many Americans use them in the same places and at the same time that they are competing with one another for use of the network. “A hundred cellphones demanding bandwidth per cell site may not be out of the question in congested downtown areas,” said Tim Pozar, a wireless engineer who installs custom repeater systems to improve cellphone coverage at offices in the San Francisco area. IPhone owners have proved to be heavy consumers of network capacity.
What to do? There is no single magic bullet to improve iPhone service. You can spend hours trying to persuade AT&T to let you out of your contract. The time you spend doing that will cost more than the contract termination fee.
Knowing a few tricks might get you a connection. If your touch screen says “No Service,” the easiest fix is to hold the phone completely vertical, rather than slanted across your cheek. The iPhone’s antenna is meant to reach furthest if it is held straight up and down. If that doesn’t work, move. Indoors, walk to a window. Outdoors, cross the street.
For the newer 3G-capable iPhones, turning off the 3G in favor of AT&T’s older Edge network is sometimes effective. Go to the iPhone’s Settings icon. Tap General, then Network. Slide the Enable 3G toggle from On to Off. But you can’t talk and browse the Web at the same time on Edge.
Another alternative is to use a Wi-Fi hot spot to make calls. Skype, the popular Internet phone service, will make and take calls as long as you leave the app running and signed in. (Until an iPhone can multitask, that means you have to have the Skype app on all the time.) Calls with other Skype users are free, but calls to and from phones cost about two cents a minute. The app is available in the iPhone App Store.
Skype call quality varied in our tests from clear to sputtery, with a delay from one half-second to three or four seconds. Also, the app works only over Wi-Fi, so you will need to juggle between Skype and AT&T, depending on where you are.
Or, for $15 a month, you can subscribe to the Line2 app that mimics Apple’s phone in look and feel, but switches calls to a Wi-Fi network whenever the iPhone connects to one.
Line2 can start a call on AT&T’s 3G network and then transfer to Wi-Fi, whereas Apple won’t allow Skype to handle calls via AT&T. If left running, it will also receive inbound calls over Wi-Fi. (If Apple were to add a Wi-Fi option to the built-in Phone app, this wouldn’t be a problem.)
But for reliable service, there is no substitute for hardware that increases range. That is why AT&T has begun offering home 3G base stations that look like Wi-Fi routers, but send and receive 3G radio signals instead. These microcells, as AT&T calls them, connect to the Internet and offer wireless coverage of up to 40 feet in any direction. They work with any 3G AT&T phone, but not with Apple’s older non-3G model of iPhone.
The catch is that you will have to pay AT&T for the boost. There are two payment plans: If you buy the microcell for $150, AT&T will charge your voice calls made using the device against the minutes on your monthly wireless plan. Or you can sign up for unlimited calling for a $20 a month fee, and get the microcell free.
Many people consider it outrageous that AT&T isn’t handing out microcells to solve what they see as a problem that AT&T created. But you do get your own personal cellphone tower without needing the approval of your neighborhood’s opposition watchdog group.
AT&T’s microcell is built by Cisco (NASDAQ: CSCO – News), a company with a reputation for solid network gear. Setup isn’t exactly plug-and-play, but it doesn’t require you to be a technician. You log in to attwireless.com — you’ll need to create an account if you haven’t already — and open a URL clearly labeled on a sticker that covers the microcell’s cable ports. Enter the microcell’s serial number and the 10-digit phone numbers of the iPhones you want it to serve. Then, as the instructions warn, you must wait up to 90 minutes while the microcell configures itself.
Call quality over the microcell was almost shockingly clear, ungarbled and free of the underwater sound that plagues many cellphone calls. You also might be less likely to experience the common many-second delays between your saying something and the other party’s hearing it. Cellular experts warn that delays and stuttering calls are still possible because these are caused by Internet traffic jams rather than the microcell.
If you make a call from inside the house and then walk outside, you can expect the microcell to reliably hand off the call to a local tower. Calls made outside, though, don’t transfer to the microcell when you get home. The only annoyance you may find with the AT&T unit is that whenever it is rebooted, as home networks sometimes are, it may take about 20 minutes to come back online.
AT&T’s solution will work for homes and small offices. But the company is clear that you can’t take it with you. It may not connect if plugged in somewhere else. So how to solve the restaurant dead-zone problem?
Mr. Pozar says the best fix is for the location to install its own repeater. For $1,000 to $5,000 in parts and labor, a hot dim sum spot could route calls through an outside antenna that connects to an inside amplifier.
That’s not cheap. But instead of a Free Wi-Fi sign, what better way to attract big spenders than one that says iPhone Hot Spot?

Engadget points to a YouTube video posted by a developer apparently showing an iPhone application called Wi-Fi Sync that will enable users to wirelessly sync their iPhones and iPod touches with their computers via a local Wi-Fi network.

As the name implies, the app promises a complete sync of your iPhone or iPod touch with iTunes without having to tether and looks pretty straightforward (and occasionally useful) based on the video demonstration found after the break.
According to comments from the developer, he believes that the application fully complies with Apple’s developer rules and will be submitting it for inclusion in the App Store later this week.
The application requires a separate syncing application to be installed on the user’s computer. The video shows a Mac OS X version of the application in action, and the developer promises that a Windows version is under development.

One thing that bugs me about the iPhone’s email program is the inability to rearrange the order of email accounts to my liking.

Unfortunately there’s no “Edit” button like Phone Favorites to drag names up or down to reorder them.
But there is a way to reorder your email accounts to your satisfaction. Here’s how:

Plug in your iPhone and launch iTunes.
Select your iPhone in the Devices column on the left, then click the Info tab at the top of the screen.
Click “Sync selected mail accounts:” if it isn’t already selected.
Uncheck any mail accounts that may be selected except the mail account you want to appear at the top of your email accounts list.

Click Sync.
When iTunes finishes syncing leave the prior mail account checked then check the mail account you want to appear as the next account on your email accounts list.
Click Sync.
Repeat step 6 for each addition

al mail account until you’ve synced them all.
