It's still good and I cannot use it now I have moved to New Zealand from the UK, because it is locked to Orange - who can offord Orange roaming NZ to UK! I cannot afford a new phone iether, anyway I like this one. I have heard all about unlocking procedures and they sound a bit scary. What do I do?
I await you intelligent nerds with great interest.

Use Omnius to unlock the phone.
Download it here http://www.omnius-server.com/download
Run the program
Click settings and then server settings
Username is Newbie
Password is newbie
Then select k550 in the drop down list
Then click the unlock button
Then select unlock network lock by reset
Follow the on screen instructions on connecting the phone
Done. 
Hi to KrazyD,
Thanks for your efforts and it may eventually work!
However, is it right to expect that after the last instruction: "Press and hold buttons 2 & 5, then connect the cable to the phone" and the start of the "Action progress" indicator to wait a very long time for a result, I mean, over an hour so far?
Should I go on waiting or is it likley something has gone wrong and should I "Abort"?
Cheers,
Chris
Thanks, KrazyD,
Thanks to you and Omnius, I seem to have succeeded, but I await confirmation when I go to a New Zealand
Telecom shop to get one of their SIMs and I will know if I am up and running. I have saved the log file in case it is useful in the future.
Best regards,
