FORMATTING A Nokia N70 Phone:
Here's how to hard reset or format your Nokia N70 mobile phone:
1) Switch off your phone
2) Press and hold these 3 keys together:
-green dial key
-the star key(*)
-the number 3 key (Ugh, I wish I had three hands...!!)
3) Power on the phone
Warning: Do not release the keys until you see a formatting screen and even after the phone has started.
Wait until the initial sound starts to play and the hand animation is displayed.
