I use my 2G iPhone w FW2.2 regularly. Today, when i try to run a software i installed through iTune, the screen black out for a few seconds and return to springboard. then i tried other wares i brought from iTune, same thing.

i didnt make any change to the phone for the last few days, and it was fine. last night, i left it on charge and this morning, all wares started crash on me.

Plz help if you know wut causes the problem. Thanks.....

btw, i tried to edit the title of the thread to [Problem], but i can't. sorry for the inconvenience.

You must authorize that computer first. Open your iTunes software, goto menu Store\Authorize computer... then type your ID and password that registerd from itune store. After that you can sync your iPhone with that computer again, and problem solved!
