Hi.

FlipSide is now available for Windows Mobile devices. You can install
OTA by downloading the CAB straight to your device, the download is
approximately 73 kilobytes:
flipside.fm/flipside.cab

Alternatively you can download the desktop installer, which is a bit
bigger at 565 kilobytes.
flipside.fm/flipsidemobile.exe

Devices running Windows Mobile 6 already have .NET CF 2 or better but
people with older devices may need to update the .NET CF, which you
can download here.
