We haven't figured that one out yet. Because the beta and final products are the same AppId, it appears that Droid keeps the first icon. If you were to do a fresh install, it would replace the icon with the non-beta icon, but you would lose all of your downloaded data, and user settings, and saved flight plans, etc. I'll put it on my list to research this more and see if there is something we can do about it. It hasn't been a high priority, because it only impacts our beta testers (a few dozen folks) and it is semi-cosmetic in nature.
