It appears that new firmware has been issued to repair centres for the purpose of defeating the FREELY available unlocking solution including clips, so beware.
I have not tested this but when upgrading to this new release 5.57.... all handsets unlocked not via logs that were previously locked to a network will be RELOCKED.
To date the only solutions available are GRIFFIN and NEELIX 2 as only downgrading appears to work.
Nokia have notified all service points to upgrade sw in any and all handsets where possible.
