The Orange C550 can be unlocked for free.

I've ordered the C550 and when it arrives I'll post the instructions I used to unlock it. If you can't wait: they can be found somewhere on howardforums.com or modaco.com, I can't remember where I saw it (I'll find the link again when I need it in a couple of days)

first you need to download this zip file onto your phone, then unzip it on your phone and change the keys detailed here: http://www.modaco.com/INFO_Decert_SIM_Unlock_C550-t222786.html

copy the cert.cab file onto your phone, and run it, then while your phone is connected to your pc, run the .exe on your PC and sim unlock your phone

need any help, just ask
