UNLOCKING Problem o2 PAY as U Go Desire

I have tried Unlocking online, HTC unlock and unlocking .com, and none of them are unable to provide a code. Has anyone managed to unlock a pay as you go o2 HTC desire? If so who is reliable, is there any company able to unlock these devices?

Thanks any help much appreciated



Hi I got the unlocking code straight from O2. I bought my phone second hand, O2 provided the code within 24hrs. It might be worth a try. They have a form on their web site to complete.
