I have an HTC Evo, which is still on Froyo. I've installed Swype and Graffiti, and while I mostly use Graffiti (I used to rock a Palm III), I switch as I need.
I heard of the Hacker's Keyboard on the Android Market and I jumped at it. I have ConnectBot on my phone and I sometimes use it to get a command line on both my home and work machine, and it seems like the right thing. But it isn't showing up as one of my choices. Just Swype, Touch Input and Graffiti.
I see "Gingerbread" in the description. Sprint hasn't pushed out Gingerbread yet. Is that the problem?
