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.
