C55 service provider unlock

[lexthekjex]

Hi all,

I am new to this, and I wonder if there is any way I can service provider unlock my C55?

Do I need a special software, and where do I get this?

Also, where do I find firmware for C55?


I need xx0203 version, I think.. is this right? It was like that for my old C45..

xx = version of firmware
02 = language of menus etc
03 = T9 pack

All help greatly appreciated!
