I have found that as I upgrade the 7230 OS from one version to the next, I do not lose the ability to run any of the 3rd party applications installed on the device. I went from 3.7.0 to 3.7.1 to 3.7.3 to 4.0.0 -- no issues with 3rd party software that I noticed. My guess is that some of the apps might LOOK a bit strange due to changed screen resolution, but I suspect that as the screen resolution INCREASES you will not lose any functionality. Of course, I could be dead wrong
