Closely resembling the HTC Magician, the device is a 2.75G phone with a 2.8" 240x320 touchscreen, a 2.0-megapixel digital camera, Bluetooth 2.0 without EDR (equivalent to version 1.2 with additional bug fixes), WiFi 802.11b/g, Infrared Technology, Microsoft Push email access, 128 MB internal memory and a full sized SD card slot (no SDHC support).
It is based on the Microsoft Windows Mobile 5.0 Professional platform, and was among the first Pocket PC phones to use the operating system.
The phone also includes Pocket Internet Explorer and Windows Media Player 10 Mobile as well as some carrier or provider specific software.
There are several "unofficial" builds of Windows Mobile 6 (Crossbow), WM6.1 and even some Windows Mobile 6.5 builds which run on this device, and now even some tools which allow users to create their own custom WM6 ROM images (a process most commonly known by the term "cooking ROM's").
There is a thriving semi-underground community of people dedicated to improving these WM6 builds (and associated tools) on the Prophet, most notably xda-developers.
