I use Touch-Commander
www.touch-commander.com and I like it a lot, it does cost money though (they are having a sale right now though.) The only gripe I have with the product is it seems buggy when using SMS-Chat from VITO (locks up sometimes, nothing a soft reset won't fix and it's not that often). The touch control is really smooth and responsive. I believe there is a free fully functional trial too. Give it a shot
