hello, i have a nokia 3360 on at&t. It has the blue LED conversion and no firmware updates or anything else. It is about 1 year old and my problem just started yesterday. When I press any button the phone shuts off and turn itself back on (sometimes, other times it stays off) and the clock needs to be reset. I didn't drop this phone in any way, nor has it been in the cold, heat etc... well any help you can give me would be greatly appreciated. Thank you in advance.
