I've just been sent mine from
http://www.unlocking SPAM link removed.co.uk/HTC/HD7/
Ordered last Thursday (when the phone arrived - ordered from 02.co.uk) but got an email saying not available and an 'agent' would get back to me. Heard back a while later saying they couldn't get the key but they would continue to check the IMEI every day until available and email me either way each day. Alternatively I could of had a refund but chose to leave it and see. Had an email everyday since and finally got my code today!
Would assume that means every other DB will be updated but not sure how it works plus it depends on when yours was manufactured. My handset only came last week but god only knows how long it was sat at the o2 warehouse.
