Just last week, BigBoss released a package on Cydia called SemiTether, which allowed users to reboot their tethered jailbroken iOS 5 device without the need to connect it to the computer. It wasn’t a full tethered boot though (hence the name) and limitations arose along with several reported issues. BigBoss recently released a new version of SemiTether (v0.91), which incorporates the new mobile substrate by Jay “Saurik” Freeman. The new semi-tethered mode is supposedly more stable.
BigBoss mentioned the following in his release:
v0.9.1 incorporates Saurik’s new mobile substrate. Thanks to Saurik, we are entirely rid of all the daemon patching – this means there’s no more daemon patching or restarting. Most the semi-tether work is now done by mobile substrate. The semitether package from the repository now protects your iOS 5 notification center plugins and gives you the option to patch mobile safari so that it will work on the non-jailbreak reboot mode. I’m still looking into patching mail, if possible.
- Much more stable with new mobile substrate
- Can patch safari so it works in the non-jailbreak reboot mode
- App to monitor the status of your semitether and reapply. Check after cydia installs.
What the semi tethered mode does is allow users who have used a tethered jailbreak for their iPhone to at least use it for some of the basic functions upon having to restart their iPhone (without having a computer nearby). Previously, because of the required tethered boot, if your iPhone for any reason was restarted, you would be stuck at the Apple logo until you went to a computer and used RedSn0w’s “Just Boot” option. With the update, you can use the Phone, Messages, and every other stock app on the iPhone (including Mobile Safari with this update). You still cannot use the Mail app (although you can use a gmail app for example from the App Store instead) and no Cydia tweaks or apps work either (which is a given).
BigBoss did provide a word of caution though regarding the updated version, which can be found below:
This new version will definitely solve all the flakiness problems we had in the past. However, be aware that this is a total rewrite of mobile substrate. Until this appears in a community source, you are beta testing so installing it is entirely at your own risk.
