We have some more good news for jailbreakers. pod2g had tweeted couple of days back that they have all the exploits needed for a new jailbreak.
He had mentioned that the next step was to bypass ASLR. ASLR, or Address Space Layout Randomization, is a technique that randomizes the memory locations of the files. This subsequently makes it difficult for an injected code to locate the rogue scripts in advance to execute an attack.
pod2g has just tweeted that he has successfully bypassed ASLR:
ASLR seems bypassed! Weird machines FTW. Time to ROP the payload.
pod2g hasn’t provided any more details, so it is still not clear if this new jailbreak is the untethered jailbreak for iOS 5.1 that we have been waiting for and will it also support iPhone 4S, iPad 2 and iPad 3.
But based on the last update, we’re assuming that it will be an untethered iOS 5.1 jailbreak for iPhone 4S, iPhone 4, iPhone 3GS, iPad 3, iPad 2, iPad 1, iPod touch 4G and iPod touch 3G.
Currently, Redsn0w that was released by the iPhone Dev team in March supports only a tethered jailbreak for iPhone 4, iPhone 3GS, iPod touch 4G and iPod touch 3G. You can only perform an untethered jailbreak on iPhone 3GS with older bootrom. You can check out our how to jailbreak page for links to the latest step-by-step tutorials.
If you’re waiting for the untethered jailbreak or jailbreak for iPhone 4S, iPad 2 and iPad 3 then we’ll let you know as soon as we have any further updates, so stay tuned at iPhone Hacks or join our Facebook Fan page or follow us on Twitter or add us on Google+ or subscribe to our RSS feed.
