What is the unlock code for the blackberry perl?
I am not an ATT customer. A friend gave me the phone to use internationaly. I need the code not the instructions. Thanks though

Hi each mobile has an unique unlock code. If you need unlock code you can visit this site Unbblock.com here you can get the code and unlock your blackberry pearl. To get the code you have to specify the following details your blackberry pearl model,which country is locked now,network provider and imei number. Then they send unlock code through email.
