I unlocked two Samsung SGH-T679M. It was very easy, took about 2 minutes for each device.
I used the USB cable connection and there was no problem.
I did pay from a Paypal account and I had immediate access.
Basically there was no problem and the result is that we now have two perfectly functional phones on any GSM network.
