Can a 3g iPhone work with ATT prepaid 3g Sim card and be able to have 3g coverage?

yes the only thing is u wont have internet... at&t is slick also when u first get your go phone it locks the simcard to the phone so u will have to get a new sim card if u activated a go phone with the sim...

I've done it with my prepaid 3G sim that they gave me when I setup a prepaid account. Just popped it into an ALREADY ACTIVATED iPhone, and you should be good to go. Data works normally, but signal isn't that good, since prepaid uses a different antennas on the cell tower for prepaid users apart from normal subscribers.
