Sure, a handful of Google Nexus One users have been rocking Android 2.2 Froyo on their handsets for a few months, but that’s a pretty small percentage of Android users overall. But it looks like the wider Android world is about get a cup full of frozen yogurt soon.
Among other updates, Google Android 2.2 Froyo brings a new Java compiler which should significantly improve the speed of third party apps on most phones. There are also home screen changes, with persistent buttons for launching the web browser and phone app. And some carriers will allow you to take advantage of another killer Froyo feature: support for tethering your phone to a computer to share the 3G internet connection.
