Finally, a semi-tethered jailbreak tool has been released for iOS 5 users! Have you ever found yourself phoneless because you aren’t near a computer and forgot you needed Redsn0w in order to restart your phone? Or needed to reboot your phone after installing a tweak? Well no worries because BigBoss has a solution to at least make your device usable until you can boot tethered with Redsn0w again.

When your device is jailbroken tethered, you will not be able to power it back on once it powers off. But the new tweak that is available for free from BigBoss allows you to reboot your device without the use of a computer and Redsn0w- but there is definitely a limitation to this (at least for now). You will not be able to access Safari and Mail until you reboot tethered. This semi-tethered jailbreak allows you to turn your phone back on if your phone ever runs out of batteries, powers off on you and all you have is a wall charger. If you need to make a phone call, all you have to do is charge your phone and you’ll be able to power it back up with all information still intact. The device will take just a bit longer to boot up than usual, but that is normal and expected because the hack is just running its effect on the device.

In order to get this tweak, you will need to add the following repo:

http://thebigboss.org/semitether

This tweak cannot be found in the main BigBoss repo, so make sure you add the repo listed. Once it is added, install the semi-tether, reboot then boot tether. Now you’ll be ready to reboot your device in semi-tethered state!

So just as a reminder after you install this tweak: Calling, texting, downloading apps, etc. all work but web surfing and e-mail will NOT until you boot tethered. The whole point to this tweak is so that you are out of the tether loop and can at least use your device if you ever needed it for an emergency. Everything will be usable and back to normal once you boot tethered again.

What are your thoughts on this tweak and will you be installing it? Let us know below!
