I recently bought a Sony Erricson w580i and I know how to set up the phone lock but i want it to show me the code or stay locked when i slide up the phone. Is there anyone that knows how to do this? ... Please let me know asap x
You can set an 'Automatic Keylock' which locks the phone if the slide is left open, it kicks in after about 10 seconds. You can use PIN's to lock the phone and SIM but as far as I know that's only for when you turn the phone to stop people from using it that way. The SIM lock is so no one can put it in another phone and use your contract.
Menu > Settings > Security > Locks > Automatic Keylock > On
To unlock the keypad you can either close the slide or press the 'top' left button then the 'top' right
