Simox:
one question.
after unlock, each time i take out the battary and put it back, the date and time will change to 8:00pm Dec-31-1999(i did not turn on the auto-update)
Before, even i take out the battary, my w580i still can hold the memory for a certain period of time (i am not sure exactly how long, but at least 30 mins)
do you have any idea?
