Hello All, I currently have an Jailbroken and Unlocked iPhone 3GS. About 4 days ago the battery started having issues. On a normal day, at most I can get less than 2 hours out of the battery. I have no applications installed, and the only thing I have configured is MobileMe. (This is without using the phone, in standby the whole time.) HOWEVER, If I turn the Cellular Data Network off, I can get through a whole day with the battery still at 100 or 99%. What could the issue possibly be? Related to Jailbreak? or do I need a new battery? Also, If i put the phone on Airplane Mode with WiFi on, the same issue happens. Thank you for your help.
