I got it from Craigslist and its blacklisted. It's T-Mobile if I unlock it and use it for AT&T will it work for AT&T?

I have an unlocked phone and used it for AT&T then sold it to my friend he uses Sprint and it worked fine
Sounds like they sold you a stolen phone. You will have to purchase an unlock online.
