So I randomly noticed today that Gmail 2.3 is available in the market, which is the highest version I've seen anywhere. It shows up in my list of downloads, but doesn't show as 'Installed.' I'm currently running 2.2.1 on rooted Inc. When I click install, it says that it is unsuccessful. Do I need to remove 2.2.1 first, and then try to install? It doesn't give the "update" option. Just want to make sure uninstalling 2.2.1 won't cause any issues.
