Hi guys, I'm new to the forum and also own a unlocked and jailbroken 3g iphone.. got it off ebay. Well heres the story, I bought the phone off ebay and it came with tons of apps and music from the original owner. so, today is when i decided to take all of the music off and add my own... ok.. done. synced everything but it had said that the applications can't be backed up or whatever and blahblah... and now... my music is all in... the applications are still there, BUT! when i try to open a few that I normally fool around with, it opens, loads but then closes, repeatedly.. I dont know what to do now....if I should probably delete that or those certain applications and reinstall them??? help? thanks.
