I'm not sure where this problem lies. I exchange SMS on a regular basis with friend who is an AT&T subscriber, with another friend who is an Alltel subscriber, and with a niece who is a Verizon subscriber with no problems in either direction. None are iPhone users.
I would start by contacting AT&T customer or technical support.
