Most of the users who’re on iOS 5 haven’t jailbroken their device yet, even those who had jailbroken before are thinking twice. Why? Right now, iOS 5 is pretty new and the awesome jailbreak developers have only managed to conjure a working tethered jailbreak for all devices except the iPad 2. So, obviously nobody would want to tethered jailbreak their iOS device.
An untethered jailbreak is however in development, as reported by iH8sn0w, but we have no time or date for the release or any updates on the work. Thus, a semitethered jailbreak seems like a better idea right now. If you haven’t heard of this term before, then let me tell you what it is. It’s somewhere in between an untethered jailbreak and a tethered jailbreak, it’s better than the latter, but comes with a catch.
Earlier today, Cydia developer, BigBoss released a semitethered jailbreak for iOS 5, which is now available for download from the BigBoss repo in Cydia. A semitethered jailbreak will let you reboot your device when away from your PC, you need not connect your iOS device to the computer every time you want to reboot. However, after rebooting, Cydia will not work, nor will any of the jailbroken apps or tweaks. Also, some of the stock iOS apps such as Safari and Mail will not work.
Now, that’s bad to an extent. But, it can be useful in certain scenarios, where you will need to reboot your iOS device, but aren’t close to your PC. You can get the Cydia package from the BigBoss repo by adding this to source: http://thebigboss.org/semitether.
Will you be performing a semitethered jailbreak on iOS 5?
UPDATE: The semitether jailbreak for iOS 5 has been updated to fix certain bugs, here’s the list.
1) Much more stable with new mobile substrate
2) Can patch safari so it works in the non-jailbreak reboot mode
3) App to monitor the status of your semitether and reapply. Check after Cydia installs.
This means that you can run Safari and all those jailbroken Notification center widgets after performing a semitethered boot. Here’s a tutorial on how to semi-tether jailbreak your iOS 5 device.
