ok, so i got myself a samsung f700. the only problem is that the phone is locked. when i say locked, i don't mean locked to the service provider. i mean there is an option to ask for a PIN number each time the phone is turned on. i have no way of finding the PIN number and i would like to avoid contacting Cingular. is there a master PIN or and type of hard reset that i can do? or anything at all that i can do?
