Palm announced that an update to the Windows Mobile 6 Professional operating system will be available for Treo 750 smartphone customers around the world. The Treo 750 is available from carriers in the United States, Europe, and Asia and remains a key part of Palm’s international expansion strategy to make Treo smartphones available to more customers. For AT&T customers, the update also will facilitate HSDPA (High-speed Downlink Packet Access) capability–allowing faster data-download speeds on 3G/UMTS/HSDPA networks.
