Some people e-mailed me with questions on the XDA Diamond aka HTC Touch Diamond smartphone. Most of these questions concerning performance and hidden features can be solved using one or several of the following tools: You can activate the hidden camera functions like GPS-Photo or Sports Mode and a lot of other things by using the Diamond Tweak. To improve the speed and settings of TouchFlo3D, please take a look at Diamond TF3D Config. Both tools don’t add own functions to the phone. They just control hidden registry settings or change the parameters of TouchFlo3D. I use both since quite some time and haven’t experienced any problems with them.
