As most know – until now, the newer Apple iOS devices (namely iPhone 4S and iPad 2) could had no untethered jailbreak solution.
An untethered jailbreak means that the jailbreak will stay in place an active even after a reboot of the device. So far only some partly efficient tethered jailbreak solutions had been released (meaning that you will need to re-apply the break using your PC/Mac after each time your reboot the device).
A few days ago, the iOS hacker Pod2g (who is a member of the Chronic dev team responsible for some of the more known prior jailbreak solutions), had demonstrated a working iPhone 4 jailbreak solution on a quick video he shared:
Following that demo, Pos2G recently confirmed that he managed to provide an untethered jailbreak for the iPhone 4S running iOS 5.0.1.
Pod2G is expected to publicly release the iOS untethered jailbreak to the world later this week but he did say that users who wish to maintain their Sim unlock on their phone should avoid updating their OS using the Apple update service. If you update your phone using the formal update your Sim will get locked (for non simfree devices) and for now – there’s no work around for that.
It is still unknown if the new jailbreak solution will work on the iPad 2 or not and if iPhone 4S will be fully supported or not so updates are yet to come and we will post them as they get released.
