I have a jailbroken iPhone4 on original iOS 4.0.1. It was jailbroken through jailbreakme.com and everything was working great up until a few weeks ago. My phone when plugged in to charge will not consistently charge, it will constantly go from fully charged symbol to charging "lightning bolt" then show fully charged when it has not reached 100%. I do not believe it is a hardware issue, as i can still sync my phone. My usb cords also still charge other iPods/iPhones with no problem. I am having this issue with both charging via USB and wall outlet. Now, I am not sure if what can be done outside if completely restoring the phone, but after speaking to some friends that are also jailbroken on iphone4 they said do not update to 4.3.3. Is there anything that i can reinstall in cydia to fix this? or can I update to 4.2.1 still although 4.3.3 has already been released? Just tired of thinking my phone has been charging all night when in reality it has stopped hrs ago and im left at 43% to run for the day. Thanks in advance!
