Hi,
Found this thread very useful when trying to get my HTC wildfire unlocked so just thought i'd post a bit of info.
I first went into town to get my fone unlocked at a local mobile shop, he said it would be £25 if my unlock code was on the old database or £40 if it was on the new one.
Not wanting to get ripped off i had a look online for something cheaper.
After finding this site i tried HTCsimUnlock.com, i payed them the £13 but after an hour when i checked, it said it was unable to find my code because either the IMEI number had been changed or the phone was 'too new'.
I did manage to get an instant refund from HTCsimUnlock.com.
I finally got my phone unlocked a few days later with
Unlock HTC Wildfire - Mobileunlocked.co.uk - Use your phone on any network it cost me £23.50 because my code was on the 'new database', they sent the code to me within 15mins tho.
Next time i buy a fone off ebay i'll make sure its unlocked, hey ho u live and learn ha. Hope this helps anyone else trying to get their fone unlocked.
