I'm currently using gmail app after some long researching for particular programs and files. This is what I have been looking for, and it's even better than what I used to use with the midlet 2.0 app with the Moto Q, it'd shut down every time you closed it unless you hit the back button far enough, whereas with this method, it'll stay open in the background like any other program(not sure if you can do multi-java apps/games, haven't tested.) I'll post this same thing in that essentials thread to see if it's even worth it to whoever owns that page for the gmail app, or most java apps at that I suppose since I've seen people asking numerous times. Using a Sprint Touch Pro, here is the latest gmail app 2.0.6;
