Can i get my (AT&T) iphone 4s?

Hooked up to (Cricket or Metro PCS)? Would i have to get it flashed or what? Let me know

No, because those are both coma networks. You can put it on straighttalk though.

No, and will only work on straight talk if its unlocked… They no longer sell att sim cards.
I have a cricket iphone, if your in PA and want to buy or trade
