I don't believe you can get a device unlocked by a carrier which is not branded or sold by them. Since this 8310 is an ATT device, the free unlock, if even available, will need to come from them. Someone please correct me if wrong, but I don't believe you can bring, say a Rogers BB to the US and have ATT unlock it.
