I'm still nursing my VZW Incredible along, but I find more and more incompatibilities as the OS gets older (rooted 2.1). Is there a "simple" way for me to patch up the OS to something a little newer so I can pick up compatibility with some apps that are no longer being supported on 2.1? In other words, can I "upgrade" what I've got or do I have to blow it away with a new OS load (which means I'd have to configure everything all over again)? I don't need jellybean or kitkat... just something a little more modern than 4-year old eclair

I am technical, but not up-to-date on mobile OS goings-on, so any hand-holding would be appreciated.
