MacCentral is reporting in an article that AT&T Wireless is teaming up with Wayport and building out their own network to provide 802.11b service (note: not a). The new service is called GoPort and will cost $69.95/mo unlimited at all locations (comparable to T-Mobile's HotSpot service at $59.95), and a variety of usage-based plans.

They are claiming 475+ locations.
