Due to the large difference between Windows Mobile phones, we can't guarantee that it works on every device, but we've had success with at least these devices:
- Samsung SGH-i780
- HTC Touch Diamond
- HTC Touch Pro
- Sony-Ericsson XPERIA X1
It may work on other Windows Mobile 6 devices too, so if you're feeling adventurous you may want to give it a shot anyway. Please let us know about your experiences!
