Microsoft's Windows Mobile 6, internally code-named 'Crossbow', was officially released by Microsoft on February 12, 2007. Mobile 6 was still based on Windows CE 5 and was effectively just a face-lift of Windows Mobile 5. With Mobile 6 also came Microsoft's new naming conventions and devices were no longer called Pocket PCs: devices with no phone abilities were named Windows Mobile Classic, and devices with phone abilities were named Windows Mobile Professional.

===Windows Mobile 5===
{{Main|Windows Mobile 5.0}}
Windows Mobile 5 for Pocket PC was based on Windows CE 5 and contained many fixes and improvements over Windows Mobile 2003.

Pocket PCs running prior versions of the operating system generally stored user-installed applications and data in [[RAM]], which meant that if the battery was depleted the device would lose all of its data. Windows Mobile 5.0 solved this problem by storing all user data in persistent (flash) memory, leaving the RAM to be used only for running applications, as it would be on a desktop computer. As a result, Windows Mobile 5.0 Pocket PCs generally had more flash memory, and less RAM, compared to earlier devices.

===Windows Mobile 2003===
{{Main|Windows Mobile 2003}}
Windows Mobile 2003 consisted of the Windows CE.NET 4.2 operating system bundled with scaled-down versions of many popular desktop applications, including [[Microsoft Outlook]], [[Internet Explorer Mobile|Internet Explorer]], [[Microsoft Word|Word]], [[Microsoft Excel|Excel]], [[Windows Media Player]], and others.

Windows Mobile 2003 Second Edition added native landscape, square screen and VGA support as well as other fixes and changes to those features already present in the original release of Windows Mobile 2003.

===Windows CE 3.0===

Pocket PC 2002 was launched October 2001, and was powered by [[Windows CE 3.0]], as with its predecessor. Some Pocket PC 2002 devices were also sold as "Phone Editions", which included cell phone functionality in addition to the PDA abilities.
