Unlock help

[shnurokk]

Good time of day. I have a huge problem, my friend a year ago bought me a gift in Apple Store USA iPhone 4g, but he did not know that it is locked by the operator AT&T, this phone is not blacklisted and not steal, when I learned about an official unlock it was very pleased, but I called them to write they do not want to talk to me.I was advised this site because there is good and helpful people who can help. I'll be very glad if there are any.

here first thing you need to do is check the baseband so do this...
Go to Settings
Go to General
Go to About

Now there should be a section that says "Baseband" tell me what that says...
