Unclock my sonyericcson k750i so i can use another sim card

you only need a DSS-25 (Syncstation) or a DCU-60 cable.
either way this cable is packed with you mobile!!

Check your phone model:
1) reveal the hidden service menu by the following (phone) key sequence:
("cursor" = navigation control on your phone! left, right, up, down)
[cursor right] [*] [cursor left] [cursor left] [*] [cursor left] [*]
2) choose Service Info
3) choose Software Info
4) look out for EPROM. if you see db2020 then your can unlock your phone by yourself.
