Good news, jailbreak developers: Apple’s recently released iOS 5 beta 2 software update can already be jailbroken using the existing version of redsn0w (a jailbreak solution provided by the iPhone Dev-Team).
5.0b2 can be jailbroken w/redsn0w from 2 wks ago http://is.gd/6eek4Y (must point redsn0w at 5.0b1 IPSW)..devs ONLY please
Currently, two separate jailbreak solutions support iOS 5: redsn0w and sn0wbreeze. Both of these provide a tethered solution, meaning users must boot from the desktop software in order to regain jailbreak functionality, if your iPhone reboots or runs out of power.
Following this tweet, @MuscleNerd added that this “trick” should work with all subsequent beta versions of iOS 5, which is certainly good news. However, he was also sure to warn unlockers to stay away from upgrading their handset to iOS 5 and jailbreaking: There is a chance that doing this will make an iPhone handset un-unlockable, because the process also updates the smart phone’s baseband. For this reason, unlockers must avoid the update until the iPhone Dev-Team gives the go-ahead.
We’ll be sure to keep you posted. For more information on redsn0w (which, according to @MuscleNerd, supports both iOS 5 beta 1 and iOS 5 beta 2), head over to the appropriate section of the iPhone Dev-Team’s website.
