Can you use a verizon iphone with at&t?

I accidentally ordered a verizon iphone 4 and it didn't show it was with verizon in the description and i have an at&t plan so can i use it with at&t or am i screwed? ;-; thanks

Sorry, Verizon uses a CDMA SIM card, which is not compatible with GSM, which is what AT&T uses. The only way it could have worked would have been if you unlocked it, but they are not compatible. You can return it, though. Sorry
