This is another code for those using sony ericsson. You can get more information about your phone. Just perform the following task - push your joystick right, then press * key, push your joystick twice to the left, then press * key again, and lastly push your joystick to the left again and then press * key.
> * << * < *
From there you can get access to service information of your phone, hours, minutes and seconds spent on calls already. While some who are on their way to purchase a sony ericsson handset can have the code in handy as it will help them to be conversant with information about the new phone.
