Apple users, who are using the Cupertino-based tech giant's latest mobile operating system, have been waiting for an untethered jailbreak. But unlike the earlier jailbreaks, the new untethered jailbreak (whenever it is released) will not be able to make all jailbreak fans happy.

Finding a jailbreak for Apple's mobile operating systems had never been easy for hackers. However, in the case of iOS 5, it became more complicated due to the two new devices supported by the new A5 processor.

This is the first time when Chronic Dev-team's French member, Pod2g, has given his work to his team members and taken up a new task.

Pod2g in his recent blog post said: I need to focus on A5 and hope I can find a path quick, and I have the feeling that Chronic-dev could help me.

So here is what I did:

I gave all the details to the chronic dev team so that can finish, test, integrate and release the A4 JB ASAP.

I'll put all my energy from now on on the A5.

Hackers, while working hard to find an untethered jailbreak for iOS 5, had been trying their luck in finding exploits which can jailbreak A5 processor devices - iPhone 4S and iPad 2.

Pod2g also succeeded in cache related problem in the A5 processor and working hard to get the final bootrom-exploit, but one more thing which can hamper Pod2g and MuscleNerd's hard work is updates of iOS 5. Apple, to solve battery issues related iPhone 4S running on iOS 5, will be releasing new updates of the operating software which can carry a patch for the new jailbreak.

The long wait of all the Apple device users to perform the jailbreak is going to be over soon as two hackers from two different Dev-teams - MuscleNerd and Pod2g - are working round the clock to find the crucial jailbreaking milestones.

Right now, two jailbreak programs are available and both are not untethered, and don't work on iPhone 4S and iPad 2.

Redsn0w is a tethered jailbreak - the user always has to connect his device to computer whenever he reboots it.  A semi-tethered jailbreak reduces the problems but still can't replace the need of an untethered jailbreak.

oth the jailbreaks are compatible with the iPhone 3GS (old and new bootrom), the iPhone 4, the iPod Touch 3G, the iPod Touch 4 and the iPad 1G. They won't work on the iPhone 4S and the iPad 2 because of the A5 processor.
