What is android 2.2?
It's an updated version of Android 2.1.
You can now get Android 2.3, which in my opinion, isn't as good
as the 2.2.
Android is a system that holds the apps, widgets and shortcuts.
You can also get an android market.
iPhone's use the Apple version of Android, but many think that
Android is better. Sorry to all those Apple fans out there.
