Yesterday I started debranding my unlocked (at a local mobile shop) k610i. First I upgraded the CID from 51 to 52, this didn't lock the phone, but after debranding it it was locked again, which I thought it would be. So I used your tool to create a patch and it worked excellent. Thanks a lot!!!
Damn rip-offs want £10-15 for unlocking!
