You can go to the Android Apr Market and download different keyboards. I recommend SwiftKey Beta X, it's for free and is absolutely amazing. There is a paid version but I prefer the beta. The paid doesn't do everything the beta does. Hope this helps you out man.
And you are able to push your phone back to Froyo. My brother did it because as of right now you can't root GB. I don't know how but there's probably some other thread dedicated to it.
Also the flext9 isn't very good, I got that as a free app of the day from the Amazon App Store and it felt counterintuitive.
