Model : All Sony Ericsson
1 - Switch ON your phone without SIM Card,
2 - Press 1 time the left arrow,
3 - Press 2 times the button * ,
4 - Press 1 time the left arrow,
5 - The message "Personalize with MNC2" will appear,
6 - You can now enter the Unlock Code we send to you.
If your phone have a "JOGDIAL" (ex : SonyEricsson K700i) you must press "down arrow" instead of "left arrow" for step 2 & 3. We mean by "Down Arrow" to direct the Jogdial down !
If you don't have an unlock code yet, you can get it in my eBay store.
