On March 15 Sprint will be rolling out the new Treo Pro device. It will be the first Palm smartphone to come with Internet Explorer Mobile 6 for a more robust mobile browsing experience. Some other business-class features include Wi-Fi connectivity, GPS navigation, full keyboard for fast email and texting and touchscreen availability.

The Sprint Treo Pro will retail for $199 after you take into account rebates and contract agreement.

Smartphones are great for many users, especially those in the business world who can use them for tracking appointments and keeping connected with the office or that boss who likes to know where you are at all times. The catch is that many smartphones require you to be tied to one service provider for years and some people don’t like making that sort of commitment.

For the folks that eschew the contracts associated with your typical smartphone, Palm has announced that the Treo Pro unlocked smartphone is now available to purchase. Palm says that the unlocked smartphone allows users to take advantage of any network they want and even use local SIM cards when traveling abroad.

The Palm Treo was one of the original smartphones. As new handsets have hit the market the Treo has become mostly overshadowed by cooler options. Despite that fact, the Treo still continues on and back in May we saw a spy shot of the new Treo 800w.

Palm has now officially launched the Treo 800w and announced that the device is a Sprint exclusive handset. The 800w will sell for $249.99 after discounts and 2-year agreement. The handset will operate on Sprint’s EVDO Rev A network for fast broadband speeds.

There are a lot of people out there rocking the Treo, even though newer and cooler devices like the iPhone are available. If you are fond of your Treo and want to keep it pristine as the day you unwrapped it, OtterBox has your back.

OtterBox has a pair of cases designed for different Treo models, the 1920 fits the Palm Treo 650 and 750 and the 1921 fits the Treo 680, 750, and 755p devices. The cases are designed to keep your beloved phone safe from rain, dust, dirt and hopefully 3-year olds– the bane of all smartphone’s existence.
