I would imagine this would work. This is what I did when I bought a T-mobile phone off of ebay. Put my buddy's t-mobile sim in it, called them up and asked for an unlock. They got it to him, I unlocked it, and put an At&T sim in it: no charge.

If this friend gives them your email address you should have the unlock code with insturctions in a few days (if not hours)
