After the launch of iPhone 4S earlier this month, there were talks about the possibility of a tethered or untethered jailbreak for the new Apple smartphone.
We already have Redsn0w 0.9.9b5 - a tethered jailbreak that works with iOS 5 running devices like the iPod touch 3G and 4G, the original iPad, the iPhone 3GS and iPhone 4 - and sn0wbreeze 2.8 beta 8 - a untethered jailbreak for the iPhone 3GS with the old bootrom. However, there has not been any jailbreak available until now for two devices running iOS 5 - the iPad 2 and the iPhone 4S.
IBTimes reported last week that jailbreakers of the Chronic Dev Team claimed to have found 5 useland-based exploits in the iOS 5 that were expected to allow them to jailbreak the new iPhone. Considering that, an iPhone 4S jailbreak was expected soon, even if the developers couldn't dump the A5 bootrom that would provide a lasting jailbreak. Here is a key update to that, but from the iPhone Dev Team.
Friday, we have come across a post by MuscleNerd of the iPhone Dev Team on his Twitter page, in which the jailbreaker revealed a preliminary iPhone 4S jailbreak with screenshots. The first picture shows a terminal window with root access to the device while the second screenshot shows Cydia on the iPhone 4S. To prove that the device is iPhone 4S, Siri is also activated.
MuscleNerd has revealed that the jailbreak is at a preliminary stage, and the Dev Team is still working on it to finally release a new tool. However, we are on track.
The tweet didn't reveal whether it would be an untethered or tethered JailBreak. There was no information either on whether the jailbreak is through a bootrom exploit or a userland exploit. In case of userland exploit, it would be easy for Apple to patch the jailbreak by releasing a new software update. But when it comes to bootrom exploit, it's not easy to patch the jailbreak as the exploit requires the processor to be changed.
MuscleNerd didn't confirm anything regarding whether they had been able to dump the A5 bootrom, but what he did reveal was that the jailbreak would be compatible with iPad 2 as well once it is made public, according to a report by iPhoneism.
When will it be Available?
MuscleNerd didn't give any public release date for the jailbreak. He hinted that developers have big hurdles in their way which they need to remove before releasing the new iPhone 4S jailbreak to the public.
Nevertheless, it is a good sign and a first shine of hope for iPhone 4S owners who are not satisfied with the restrictions imposed by Apple.
