Looks like there is yet another loophole in the iOS for iPhone, iPod Touch and the iPad. Pod2g is once again in the news as the guy behind SHAtter and Greenpois0n’s untethered iOS 4.2.1 exploit is the one making the discovery. Reports state that this can be used for the iOS 4.3 as well.
I have no details on whether this exploit works around on userland base or like the Limera1n depends on the bootrom. Other than this, I guess Pod2g will keep this in the pocket for later releases of the iOS 4.3 since Greenpois0n is already set to bring untethered jailbreak to iOS 4.2.1. We will be updating more on this as more information seeps through the developer team, so stay tuned.
