Activate iPhone without Official Carrier Sim; Fix Poor Battery Life Issue after Unlocking

Poor battery life was observed by iPhone users after they unlock their handsets using the combination of PwnageTool or Redsn0w to update baseband to 06.15.00 and Ultrasn0w 1.2 for iOS 4.2.1.


Be worry free since the developer of the application already figured out to fix the issue of poor battery life of unlocked iPhones. The developer recently released a jailbreak app called SAM (Subscriber Artificial Module). Even if you unlocked your iPhone with Ultrasn0w, it tricks your iPhone and iTunes into legitimate activation tickets.

Thanks to this wonderful application and you will get the full-blown benefits of the push applications and also addresses the poor battery life issue that you may encounter after unlocking your iPhone. The iPhone Dev Team said that developer @sbinger hit two birds with one stone.

You can follow these simple steps to install your jailbroken iPhone with SAM.

•Install “SAM” and “SAMPrefs”


•Follow the steps in Troubleshooting/Hacktivated with redsn0w or PwnageTool
