[Q] touchscreen digitizer /virtual keyboard alternative

view story

http://forum.xda-developers.com – Hi my digitizer/touchscreen has deadspots can only type p and L on with keyboard even though i managed to still root and install cyanogen mod 7 but the trackball seems to be the only thing that will let me select anything and i dont want to spend the money on a new touchscreen for it or digitizer and go through that headache on this outdated phone so was just wondering if you guys knew of a virtual keyboard app that would utilize the trackball feature of the htc droid eris and let me use it to select that letters to type there by getting a quick fix for the prob besides having to sink money in (HowTos)
