Does AT&T have good coverage in Maryland?

If I were you, I would wait for the HTC EVO to drop June 4th from Sprint. 4G with WiMax brother! No 4G in Frederick yet, but there is in DC and Baltimore while still having 3G in Frederick. That's just my opinion. ATT has decent coverage around this area. All my friends have them. I have just always been partial to Sprint and their package prices. I live in Frederick and also do a lot of work in DC / Baltimore area. I've never had a dropped call. look up the EVO dude, the phone is SICK!!!!!!!!
