I've had some bizarre problems with my Vario III lately. Basically only when charging in the car, the phone appears to be charging (orange status light by earpiece lights up, battery status screen shows the phone is charging) but no charge appears to be taken (the battery level keeps dropping). Then after 2 or so minutes, the orange status light goes off but all else remains the same (backlight stays on etc). This is the same in my cradle wired directly to the stereo power and from several cigarette lighter car chargers. Works fine with other phones.
Anyway, T-Mobile have agreed to exchange the device, but I have a slightly cooked ROM on it at the moment. Should I revert back to the original ROM before sending it back and if so does anyone have the original Vario III ROM available!
