Can you use an AT&T iPhone on straight talk?

I just wanted to know if a AT&T iPhone 4, will work with a straight talk plan. The phone is not active with a plan right now… What do I have to do to it to be able to use it on straight talk… Does anyone have an iPhone on straight talk?

Sure, you just have to get it unlocked. Make sure you get the AT&T plan from straight talk, the T-mobile plan will give you slow data because of compatibility.
