Unlock AT&T Blackberry 8820

I received a Blackberry 8820 locked by AT&T. To use it in Canada with other carriers, I need to unlock it.

First I Google it, and got a bunch of sites.
I order one from Wireless Unlocking. It is cheapest. Only $7.99. I sent my payment with IMEI code. After two days waiting, they told me they can not get the unlock code for me. Then I got the refund in a week.

The second unlocking service I used is HorizonWirelessOnline

It is very fast. I got the code in 48 hours.

They all accept Paypal or credit card.

The procedure to enter the code and unlock shown as below.
