The iPhone Dev Team has an untethered-jailbreak for iOS 5.0.1 released. The jailbreak only works on older hardware. Until now it was only the tethered-jailbreak is still available, where the need for a pc to boot.
The untethered-jailbreak by the iPhone Dev Team has released will not work on hardware with an A5 cpu, allowing users of the iPhone 4S and iPad 2 the method does not apply. The jailbreak is available as a Cydia package, for users who have their device already gejailbreakt.
‘New’ users can get the updated version of the redsn0w-jailbreak-tool. Who still does not have iOS 5.0.1 running and still want to jailbreak, are advised to are software first. Until now there was only a tethered-jailbreak available: it is the need for a pc to the phone or tablet to be able to boot with a working jailbreak.
The developer of the jailbreak are working on a way to exploit even on hardware with the A5 cpu’s to be able to apply. To accomplish this, a new vulnerability must be found.
