While the HTC HD2 has multi touch capabilities, many applications neglect to use it, something which Zooomer addresses pretty neatly. The next version of the great app is now here. Â It comes without change log, but it does come with a slightly detailed video.
If you have an HD2, then you should have this app, if you do not, you are not experiencing the device to the fullest.
Get the application, and feel your device.
