Windows CE 3.0 is called Pocket PC2002 now and is only available for ARM processors. As an innovation the Bluetooth support was introduced. Pocket PC 2003 has a real time Kernel with Windows CE .NET 4.1 technology, uses the features of the XScale CPU completely and takes advance of the extended instructions of the ARM v5-architecture. The Pocket Media player can play videos in the Windows-Media 9 format now. A WLAN-Stack was added and the connection settings simplified.

Windows Mobile 2003 SE from March, 25. 2004 for Pocket PCs can switch over the display contents between the portrait and landscape format and displays up to 480 × 640 pixels. The start menu was changed light and the handwriting recognizer software Transcriber is controllable with Shortcuts now. The Internet Explorer converts web pages to a adapted format for better view on small displays.
