If you have a rooted Motorola Backflip then you are now able to enjoy multitouch goodness on your phone. Keep in mind that (besides needing to be rooted) you need to run a custom ROM and neither of these are supported and if you brick your phone your kind of on your own. But with that said it is out there and available.
We've got quite the discussion about this already going on here: http://www.attdroids.com/forum/motor...ultitouch.html
You can download a ROM supporting it here: ModMyMobile
