At the standby screen type the code:
*#7370#

or hold down the following 3 buttons when you first switch the handset on:
[Green, pick up call] + [3, def] + [*+]

Be warned this will delete all information on the handset and return the handset to a 'fresh out of the box' state. All contacts, installed applications, calender entries, including YOUR PASSWORD will be lost.

Thank you.
