Head on over to PPCSG for some rather cool TouchFLO 3D themes for your HTC Diamond / Touch Pro. The entire selection is available to browse and download from mobile-sg.com including this one here called “Coffee Lover”.
They’re simple enough to install, just grab the CAB file, copy it to your phone, disable TouchFLO 3D through your Today Plugins, run the CAB and then re-enable your TouchFLO 3D. There’s a more thorough set of instructions in this post if you get stuck. If you’ve had enough of the new theme just switch back by un-installing through the settings menu. At the time of writing there’s over 40 to choose from, so you should find something to suit you. These are all the work of “Bongsu3”.
