SHAtter iOS 4.1 Jailbreak, Tethered Jailbreak For All iOS

Previously I posted about MuscleNerd confirms iOS 4.1 jailbreak tool, and the news of the possible iOS 4.1 jailbreaking is getting clearer now. We have a one guy, called Pod2g from Chronic Dev Team managed to find a bootrom exploit to make you able to jailbreak iOS 4.1.

Apparently Pod2g has found the S5L8930 chip, Apple’s A4 chip. The chip name we see inside iPod Touch 4G, iPhone 4 and iPad.

So what's the use of this bootrom exploit? With it you can execute the unsigned code to use in generating a tethered jailbreak named SHAtter, or the jailbreak for life.

One thing need mentioning that if you use tethered, you have to reapplied each time iOS device of yours is powered down. Or if your iPod touch battery run out or being restarted, reapply the jailbreak by connecting to computer is needed.

The good thing with the tethered jailbreak can be applied with both latest and older iOS firmware, because Pod2g managed to find the exploit on Apple's A4 chip on iOS 4.1

Apple will not be able to fix this exploit simply by releasing software update like it did with the previous firmwares (JailbreakMe case) albeit bootrom exploit is categorized as a low level exploit. Apple is only be able to prevent the jailbreaking using devices update with a new bootrom in order to patches the exploit. But it's impossible for Steve Jobs's company to halt you to jailbreak your devices with the older bootrom.

Unfortunately this tethered jailbreaking tools for all iOS devices are still a work in progress by Chronic Dev team and iPhone Dev team, thus, we are expected to wait.
