A beta update has been released for BigBoss’ SemiTether iOS 5 jailbreak, fixing some minor issues in the exploit, which allows jailbreakers to reboot their iOS 5 device and its jailbreak successfully without plugging it into a computer.

“Last weekend, BigBoss had released a new package on Cydia called SemiTether, which allowed users to reboot their tethered jailbroken iOS 5 device device without the need to connect it to the computer,” a Sunday iPhone Hacks article reads. “However, BigBoss’s solution had some limitations and number of users reported issues after using it. BigBoss has released a new version of SemiTether (v0.91), which incorporates the new mobile substrate by Jay Freeman a.k.a saurik that should make the semi tethered mode more stable.”

SemiTether is certainly a step up from tethered jailbreaks, which require that users hook their device up to a computer every time it’s rebooted in order for the exploit to work, but not quite as desirable as an untethered jailbreak, which makes performing such an action unnecessary.

An untethered iOS 5 jailbreak is currently being built by the iPhone Dev-Team, but SemiTether is the best option iOS 5 users have for now. It’s unclear when the latest version will exit the beta stage.
