There are untethered jailbreaks for iOS 5.0.1 and iOS 5.0 (iOS devices vary), but there is not yet one for iOS 5.1. A5 iOS device users can't jailbreak iOS 5.1 at all. The only jailbreak available for iOS 5.1 is a tethered jailbreak for A4 devices and an untethered jailbreak for older bootrom iPhone 3GS models. However, that’s not to say an untethered jailbreak for iOS 5.1 isn’t coming. iOS hacker pod2g is considering it very thoroughly.
While the iOS 5.1 firmware is widely distributed on newer iOS devices being sold in stores, large quantities of people are comfortably jailbroken in the untethered manner, running iOS 5.0.1. Users with older iOS devices such as those of the A4 breed can easily restore their iOS devices back to iOS 5.0.1 after an iOS 5.1 upgrade, assuming their APTickets and SHSH blobs are saved (if you don’t have them, you’re out of luck) – this gives them the incentive to re-jailbreak at their leisure. Unfortunately, A5 device owners do not have the ability to downgrade firmware due to the lack of a bootrom exploit. Because of this, some people are now stuck on iOS 5.1 after upgrading.
If you take a moment and head over to pod2g’s blog, a poll post will welcome you. The poll wants to know if you think pod2g and the rest of the Dream Team should spend their time finding a way to create an untethered jailbreak for iOS 5.1 (wasting exploits as they go), or if they should wait until the release of iOS 6 to start building a new untethered jailbreak.
Illustrating the jailbreak community, the majority of people seem to be voting toward the iOS 5.1 untethered jailbreak (currently around 55% of votes want it), however waiting for iOS 6 is followed closely behind (currently around 41% of voters would prefer it). Do you think pod2g should wait for iOS 6? – or should he get started with iOS 5.1?
