Windows Mobile (Platform)
Windows Mobile 6, formerly codenamed "Crossbow", was the version of Windows Mobile released on February 12, 2007 at the 3GSM World Congress 2007. It comes in three different versions: "Windows Mobile 6 Standard" for Smartphones (phones with touchscreens), "Windows Mobile 6 Professional" for Pocket PCs with phone functionality, and "Windows Mobile 6 Classic" for Pocket PCs without cellular radios.
Windows Mobile 6 is powered by Windows CE 5.0 (version 5.2) and is strongly linked to the then newly introduced Windows Live and Exchange 2007 products. Windows Mobile 6 Standard was first offered on the Orange's SPV E650, while Windows Mobile 6 Professional was first offered on the O2's Xda Terra. Aesthetically, Windows Mobile 6 was meant to be similar in design to the then newly released Windows Vista. Functionally, it works much like its predecessor Windows Mobile 5, but with improved stability.
To improve security Microsoft added Storage Card Encryption so that encryption keys are lost if device is cold-booted. Further updates, both security and feature wise, can now also be provided using Operating System Live Update.
Among other improvements: 320x320 and 800x480 (WVGA) screen resolution support (The S01SH or "Em One" by Sharp was the first and only device to have an 800x480 screen on WM5), Improved Remote Desktop access (Available for only certain Pocket PCs), Customer Feedback option, Smartfilter for searching within programs and Unlicensed Mobile Access (UMA) support for select operators.
