Wi-Fi is coming to AT&T’s BlackBerry handset customers. AT&T and Research In Motion have announced their first cellular and Wi-Fi BlackBerry handset–the BlackBerry 8820–will be available beginning Sept. 20 through AT&T wireless.

The global Wi-Fi capabilities of the BlackBerry 8820 from AT&T complement AT&T’s domestic and international wide area wireless data coverage. AT&T enterprise customers can use the BlackBerry 8820 with their corporate campus Wi-Fi networks for additional data coverage. Individual customers can use it in their homes and, for an additional charge, at thousands of Wi-Fi locations throughout the U.S., including any of the 10,000 AT&T-owned or branded hotspot locations in the U.S. Users can also take advantage of tens of thousands of hotspots around the globe through such services as AT&T Wi-Fi roaming.
