Sprint customers who own either HTC Touch or Mogul can now update their handset to Windows Mobile 6.1.
The Touch will now support Sprint's high-speed EV-DO Rev A. network, and will take advantage of the popular Opera web browser, and improved GPS functionality.
The HTC Mogul receives the same Windows Mobile 6.1 Professional upgrade. It will have updated versions of Microsoft Office and Live Search, as well as support for Sprint TV service.
Both updates can be downloaded directly from HTC.
