BigBoss has pushed an update to the semitethered jailbreak that brings multiple bug fixes and speed improvements. Version 0.7.9 of SemiTether is available in Cydia now for folks on iOS 5 that have jailbroken with a tool like RedSn0w.
The SemiTether jailbreak is being improved to make it a more viable contender to a full untethered jailbreak. BigBoss is working with saurik to improve his jailbreak alongside a mobile substrate Cydia update.
- Device does not sync with itunes and only errors. Hopefully solved.
- Device reboots after 2-3 minutes.
- App sync issue – this is unworkable. Appsync hard patches system files and does not even use mobile substrate. I had to conflict with it. For now, semi-tether boot is impossible with appsync. You guys need to bug those guys to fix appsync to use mobile substrate (like everyone else uses).
BigBoss also notes:
“Saurik is working on an update to mobile substrate that will solve many of the issues with the semi-tether package. Hopefully this will be out in a day or two. At this time, we can finalize beta testing. I plan to hold further updates until after Saurik has released his mobile substrate update. Saurik’s updates will eliminate the need for the long 90 second respring on boot also.
This update was only tested on iphone 4. After saurik’s mobile substrate changes, more devices will be tested. Next updates coming in next 2-3 days.”
Once you perform a tethered jailbreak on a compatible iOS 5 device with RedSn0w, you can install the SemiTether package from the BigBoss repo in Cydia. A semitethered jailbreak functions almost exactly like an untethered jailbreak, except that you can only use certain stock iOS apps after a reboot until you connect your iDevice to a computer and execute a tethered jailbreak again.
If you’re confused about the difference between a tethered, untethered, and semitethered jailbreak, we explain it all here.

Let us know what you notice in this update to SemiTether. Has the reboot time been improved significantly? Have you noticed any other improvements?
