Bellsouth did have some in NO and Baton Rouge. Most of La and Miss's 2.3/2.5G is owned by Sprint(was Nextel, was Worldcom, was Wireless One which had most of the SE USA for video service in the late 90's and did some limited 2way wireless internet until '03 when Worldcom sold that off to Nextel).
I live in rural Mississippi. I would love to see this happen, but I am not holding my breath.
