Can I jailbreak iPhone 4S untethered?
UPDATE: The iPhone 4S can now be jailbroken untethered. See these instructions on how to jailbreak your iPhone 4S with Absinthe.
Although the iPhone 4 and iPhone 3GS running iOS 5.0.1 have been jailbroken untethered, the exploits used currently only work on devices with Apple A4 hardware.
Since the iPhone 4S and iPad 2 feature the newer A5 system-on-a-chip, further exploits must be found to bring the untethered jailbreak to these devices. Developers are working on an iPhone 4S solution but the software is not ready for prime time.Learn more about tethered vs. untethered jailbreaking and semi-untethered jailbreaking on iOS devices.
