[Problem] all softwares installed through iTune don't work
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.....
