iOS 4.1 Jailbreak Labeled “SHAtter”

More details about the upcoming iOS 4.1 jailbreak have started surfacing. It appears to be a good news vs bad news scenario with the latest details on the previously mentioned iOS 4.1 jailbreak exploit. The good news Apple won’t be able to stop the iOS 4.1 jailbreak without releasing new iPhones, iPad & iPods with patched firmware. If you currently have one of these devices they will not be able to kill this exploit with a simple software update.

That’s right, you read that correctly. In the recent flurry of the iOS 4.1 release, there has been some great breakthroughs in regards to jailbreaking your iDevice. posixninja and pod2g have discovered the first exploit of the S5L8930 chip, aka, the A4, which allows the use of unsigned code execution in order to create a tethered jailbreak, which as far as current hardware released is concerned, a jailbreak for life. This particular chip is used in the iPad, iPhone 4, and iPod Touch 4G.

The bad news is that this iOS jailbreaking technique requires that any time you restart the iPhone you must reapply the jailbreak. If your iPhone required rebooting for whatever reason, should you let it run out of battery, you would then have to tether your iPhone to a computer and re-jailbreak the device using SHAtter again.
