Unlock service provider: insert sim, turn phone on & press volume up(arrow key) for 3 seconds, should say pin code. Press 'C' (call) then '*' message should flash, press * again & 04*pin*pin*pin# for fun: change closed caller group ( SETTINGS>SECURITY SETTINGS>USER GROUPS ) to 00000 & your phone will sound the message tone, when you are near a radar speed trap, setting it to 500 will cause your phone to set off security alarms at shop exits, great for practical jokes.. Hehe..
