SBC does WiFi installation (it's an ADSL provider) and Cingular plans to do 3G (well, EDGE) and they're getting together.

The announcement is that: "In addition to establishing hot spots at primary venues, SBC companies also plan to provide a turnkey product that enables small-business customers to quickly become a hot spot and differentiate themselves in the marketplace. The businesses would then offer Wi-Fi access to their customers."
