The mobile phone's Windows Mobile for Smartphone OS allows users to access email and the Internet, use MSN Messenger, and view documents in Microsoft Office formats (with third-party software) much like other Windows smartphones such as the Samsung SGH-i600 or HTC Tanager.
Previously, smartphone platform devices could only be purchased in the United States as part of development kits sold by Microsoft.
A common complaint about this device is that it continued to ship with the WM Smartphone 2002 operating system even after most competing Windows smartphones like the Samsung i600 or HTC Voyager shipped with Windows Mobile 2003 or at least offered an official upgrade path.
However, this led to the release of leaked unofficial upgrades for the MPx200 over the internet, with the community constantly improving them and eliminating the existing bugs.
It is generally believed that it has some kind of hardware support for IO devices but the lack of drivers for the MPx200 does not permit the use of this function for other possible addons.
