The HTC Touch HD features HTC’s TouchFLO 3D interface, but this doesn’t mean other HTC mobile phones such as the HTC Touch Pro and HTC Touch Diamond need miss out on TouchFLO 3D goodness.
Thjis reason for this is because the ever enterprising developers over at xda-developers have now been able to port the HTC TouchFLO 3D interface over to the HTC Touch Diamond and the HTC Touch Pro.
Apparently the instillation is a simple process, a matter of installing a cab.file containing the new TouchFLO 3D payload and after which installing a secondary cab.file which houses bug fixes. For all relevant info and files hit up the source.
