XDAndroid is the open source project to port Android operating system to series of HTC phones based on Qualcomm MSM chipset. Those are the HTC Raphael/Diamond, Topaz, Rhodium, and Blackstone. XDAndroid's latest release was based on Foryo (FRX07) which was released on 15 July 2011. As Android OS is not supported for these devices therefore there will be some bugs and also all Android features may not work, thats why developers frequently releases bug fixes and support for new features. XDAndroid may be act as dual boot option along with Windows Mobile operating system.
