• SemiTether iOS 5 jailbreak by BigBoss

    BigBoss has released a Cydia tweak called SemiTether that will allow your iOS 5 tethered device to boot into a semi-usable state when you cannot access a computer to boot with redsn0w. This can be used when your device accidentally is turned off so that you are not completely without your device. Once you get to your computer, you can use redsn0w to "just boot tethered" again to restore complete usability to your device.

    HERE is a guide on how to install SemiTether.

    Here is a summary of what you can and cannot do during the semitethered boot:
    1. Can use phone, sms (text messages)
    2. Can use every other stock app on iphone.
    3. Cannot use mobile safari
    4. Can use other appstore web browsers such as atomic web browser
    5. Cannot use mail app. You could install a gmail app from appstore or such instead.
    6. You cannot use any jailbreak tweak, app, cydia until you boot tethered.
    7. While in the semitether booted state, you should not add a jailbreak ios5 notification such as sbsettings to notifications during this state or your device will be stuck in a respring loop until you get home to “boot tethered”.
    From BigBoss:
    As you may know, iOS5 currently has a tethered jailbreak. This means that after you have jailbroken and installed most stuff you care about, you go to reboot your device, and it will no longer boot. You will be either stuck at apple logo forever, or you will get to itunes restore screen. When this happens, you have to hook up to your computer and use redsn0w “just boot” feature which gets you rebooted successfully again. It’s not all bad, as iOS5 is pretty stable. But if your device crashes and reboots while you’re out on the road, you are screwed and without a phone until you get home.

    An untethered jailbreak is one that does not have such problems. Here you can reboot and the device reboots successfully. Because we are using the limera1n exploit discovered from Geohot last year, we are always guaranteed a tethered jailbreak on last generation devices. A new exploit will need to be found to untether us.

    To get us through this period, I have worked on a semi-tethered solution. The semi-tethered jailbreak will allow you to reboot on the road, but with limited functionality. It is enough that you are no longer stranded, and you can use your phone, text, and many other features. This is just until you get home and can use redsn0w again to “just boot tethered”. Once you do that, you’re back to fully functional state.
