From BigBoss comes good news for anyone with a Tethered iOS 5 Jailbreak.
There is an application that has been released that allows you to make a Tethered Jailbreak a Semi tethered Jailbreak, which lets you restart or shut down your Tethered device you have and turn it on or off as many times as you want, without having to re-use Redsn0w and a computer (Mac or Windows).
This Semi-tethered Jailbreak only lets you use your iPhone or iPod touch with basic functionality, but to re-use all functions you still need to re-open and use Redsn0w to reapply a Tethered Jailbreak.
The operational functions with this Semitethered Jailbreak are:
The phone and SMS.
Browse with some applications but not with Safari.
Email does not work and Sbsettiings.
To install you have to add the repository to Cydia http://thebigboss.org/semitether, then restart the iPhone and use Redsn0w with the “Just Boot” function so that you will have a Semitethered Jailbreak.
