Amid iPhone fever, Sprint announced the launch of Palm’s latest Treo 800w; a Windows Mobile 6.1 Professional handset designed for business users. The Treo 800w runs on Sprint’s mobile broadband network with support for EV-DO Rev. A data speeds, as well as Wi-Fi and GPS. The handset also includes: a full Qwerty keyboard, 5-way navigation and 1-touch buttons to the most-used applications.

“Palm is adding a unique stamp to the Windows Mobile experience with the Treo 800w,” said Stephane Maes, vice president of product marketing for Palm, in a statement. “It’s an easy-to-use feature-packed smartphone that will keep users happy, empowered and productive.”

Along with Wi-Fi and GPS, Palm’s enhancements on the Treo include: Today Screen enhancements that let users call, text, e-mail, search the Web and map a contact’s address all from the Today Screen; voicemail controls that include VCR-like icons, such as rewind, delete and fast-forward, for easy voicemail navigation; and ignore with text in which users can ignore a call quickly by sending a text message, such as “in a meeting” or “can’t talk right now.”

Along with Palm’s and Window’s handset feature upgrades, Sprint announced that it expects new business applications to be available soon as part of its recently launched Professional Developer Program.

The Treo 800w is available through Sprint or Palm for $249.99 after discounts and rebates with a 2-year contract. Along with the Treo 800w, Sprint recommends an unlimited data plan.
