SemiTether Boots Up Tethered iOS 5 Jailbreak iPhone without Computer

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic!

If you’re out on the road with your tethered jailbroken iPhone running on iOS 5, what happens when you ran out of power and you don’t have your computer with you? Are you scr*wed? Well, not really, thanks to SemiTether.

SemiTether allows you to reboot your tethered jailbroken iPhone without a computer. However, the biggest downside with it is that you won’t be able to use Mail, Safari and Cydia until you reboot your iPhone using Redsn0w or iBooty.

For ultrasn0w unlockers, please note this won’t work for you because ultrasn0w will not work if your iPhone is booted with SemiTether. MuscleNerd had confirmed this:

“ultrasn0w needs JB so if you were semitethered and rebooted away from computer, ultrasn0w won’t work”

You should already know by now in order to boot tethered it you would usually launch Redsn0w > Extras > Just Boot. Your iPhone will then boot into tethered state and you can use Safari, Cydia without any issue. iBooty is an alternative tool if your firmware was custom made with sn0wbreeze.

Despite this shortfall, it will come in handy when you’re out on the road.

Here’s how to install it:

1. Launch Cydia and add the following URL to your source:

2.¬† Once added to your source search for SemiTether. Be sure to read the notes¬† by the developer as there are several “caveats” with it. Oh, this requires iOS 5.

Once installed, go ahead and try it. The next time you need to reboot your iPhone you can do it without using redsn0w.

Let us know what you think!
