I have a rooted Droid X, happy with it. In the settings | about phone, it says I have Android version 2.2, but the system version is 2.3.15.MB810.Verizon.en.US Am I missing something or why do these guys use Android 2.2 but system 2.3? Also, any reason NOT to let it do the update? It apparently will continue to nag me until I do. thanks.
