I just did a google search and got the hacked version that doesn't do a device check. Unfortunately it's always asking to update, but not the biggest upset in the world.
I'm using the gingerbread keyboard from the market place. It's not bad, but there is this menu button on the bottom row that makes the space key smaller and it screws me up from time to time. I'm going to try better keyboard 8 and swiftkey.
Really happy with the battery life on this phone. I've had it for a few days now and it beats away my Nexus 1 and Infuse that I previously had. I am also running JuiceDefender Plus on it, but no readings quite yet as to how good of a job that is doing.
