iPhone 4.0

Cult of Mac has learned that a Walmart store in Edmond, Oklahoma has reduced the prices of the iPhone 4 and 4S AT&T models. The 8GB iPhone 4 on AT&T is now $34, and the white and black 16GB iPhone 4S on AT&T is now being offered for $114. The new prices only apply to AT&T upgrades and new activations. AT&T has not confirmed if this is a carrier sale or a Walmart only promotion. It's also unclear if all Walmart stores are participating. However, you may want to visit your local Walmart to see if these new prices are available in your area.

Corona developer pod2g tweeted a quick update about his iOS 5.1 jailbreaking progress. The iPhone developer wrote: "Heya! My iPhone 4 running iOS 5.1 is now untethered." In April, pod2g announced that he had acquired all the exploits required to complete a new jailbreak. This latest announcement is good news since it shows that he has made some progress since we last checked in with him.

iOS hackers have been busy working on a new exploit since the release of the iPad 3 in March. Dev Team member MuscleNerd and Chpwn both tweeted pictures of a jailbroken iPad 3 running Cydia 1.1.5 shortly after the tablet was released. However, Chpwn warned that a new jailbreak "could be months away from a public release."

One week after the Chronic Dev and iPhone Dev Team helped pod2g release his untethered iOS 5.0.1 jailbreak for A4 devices, the iPhone hacker tweeted that the A5 version is only a week away from a public release.

Pod2g enlisted the aid of the Chronic Dev team to release his A4 exploit so he could concentrate on A5 devices. The A4 untethered jailbreak was released on December 27 while iPhone 4S and iPad 2 owners were once again left out in the cold. That is all about to change in the near future according to pod2g.

iPhone hacker pod2g released a video showing off his new iOS 5.0.1 untethered jailbreak working on an iPhone 4. The new untethered jailbreak should be "ready for prime time" in a few days according to his blog. The exploit does not work for the iPhone 4S or iPad 2, but it will work with other iOS devices. Pod2g previously uploaded a video to YouTube showing the exploit working with an iPod touch, and it has been tested on an iPhone 3GS and iPad.

The video shows the jailbreak working after the iPhone 4 has been switched off and on proving that it's untethered. It uses the same code patches as redsn0w, so it should feature the same level of stability. Earlier this week pod2g posted two updates on his A5 jailbreaking progress.

The good news is iPhone hacker pod2g is still working on his promised untethered iPhone 4S jailbreak. The bad news is he's having "processor cache" issues. Pod2g wrote on his blog:

"Here is the news of the 4S week-end.The untether fails right now because I'm having processor cache issues. I'm close, but I can't figure out what happens. It certainly has something to do with the Cortex-A9 cache management.I could sort it out quick, it's a matter of chance."

Pod2g excited the jailbreaking community when he successfully tested an untethered jailbreak on an iPod 4G and iPhone 4 running iOS 5.0.1 a few weeks ago. Currently their is no jailbreak for the iPhone 4S, but recent progress by pod2g and the Chronic Dev Team point to one being released soon. Pod2g promised another update on his progress tomorrow.
