Hey guys, I dont know if this helps, but after testing my EVO 4G with the multitouch tester app and confirming thats the device only allows two touch points I became depressed. The reason, because I enjoy playing Chrono Trigger on my SNESoid app, but when I came to a part in the game where I needed to press L Trigger + R Trigger + A, I found that I could not press all three buttons at the same time. After playing around the button assignment I found that you could add the physical volume button on the side of the Evo as the third button. This solved my issue and I was able to continue playing Chrono Trigger. I know that this is a stupid solution and that It would be a million times better to be able to use more than two touch points on the screen, but at least this will allow you to continue playing your game if you have the same issue. The button assigment process goes like this:
1. Menu
2. Settings
3. Input Settings
4. Key Mappings
5. Then assign whatever 3rd button you want available to the volume button when prompted for assignment
