My 3g[S] is jailbroken now though i dont see why that would matter. The last two nights ive charged it fully and the next days it wont record my usage. Its always done it fine in the past. It just has a - on both of them standby and usage. I thought maybe it was my charger i used the wall charger that specifically came with my 3gs but i used my ipod cable cause the other one was in my room. So last night i used the actual 3gS cable and still the same thing. Anyone else have this problem? ive tried rebooting etc. just dont wanna restore now that i finally have a bunch of goodies on it. thanks for reading.
