iOS 4.2 is due to be released anytime now, Apple hasn’t officially announced the release date, but they said it would be here in November. Not too long ago, Comex announced on Twitter that the jailbreak for iOS 4.2 will be untethered. While current devices have/can be exploited and jailbroken permanently without the possibility of a patch, the jailbreak being tethered has still been an issue.

The difference between an untethered jailbreak and a tethered jailbreak is that, using a device with a tethered jailbreak, you must reconnect to a computer every single time you reboot, essentially, you must re-jailbreak when ever you reboot or your device powers down.

Comex has developed userland exploits for star, limera1n and greenpois0n, keeping them all untethered.

Comex said that people with SHSH blobs saved for iOS 4.1 should be able to keep their jailbreak untethered for 4.2, he did not mention however, if this would be the case for all users. I have not seen the reasoning yet, but anyone wanting to jailbreak iOS 4.2 make sure their SHSH blobs are saved. iPad users should also save their 3.2.2 blobs in the event that they are required, just in case.

Also, separately, Comex tweeted that there may be a delay with the 4.2 jailbreak release due to compatibility issues with Cydia, which are currently being dealt with.

What do you think? Can’t wait for the iOS 4.2 jailbreak? Drop us a line!
