While the first beta version of iOS 5 has already been jailbroken, the solution developed (and announced by @MuscleNerd) was a tethered solution. This means that users have to connect their iPhone to a computer, and boot it while connected, in order to regain jailbreak functionality. In short, it’s extremely annoying and not at all practical.
Now, we’ve heard from iPhone Dev-Team member @i0n1c (via Twitter) that the current untethered exploit may have been corrected by Apple in iOS 5, meaning a new exploit will have to be discovered before users can apply an untethered jailbreak solution to their iPhone handsets.
According to @i0n1c:
R.I.P. – I just heard Apple killed the ndrv_setspec() integeroverflow and his friends in iOS 5.0b1 – if this is true the untether is dead
In short, it’s very unlikely that an untethered jailbreak solution will be developed before iOS 5 is released to the public. Furthermore, it remains to be seen as to whether an untethered exploit for iOS 5 will be discovered at all. If you’re desperate to jailbreak, limera1n’s bootrom exploit will provide users with a tethered solution. However, as mentioned, this certainly isn’t ideal.
We’ll keep you posted.
