The guys over at XDA Developers have taken a leaked version of the HTC Hero’s Android firmware and managed to install it on a T-Mobile G1.  What does this mean?  This means we get a nice preview of the newest version of Android, and it has a number of cool new features and options.  The new Android OS features a nice, new interface that even features some elements that are very similar to HTC’s TouchFLO 3D interface.  The web browser in this new OS features flash support, and for those who can’t be away from their social networking sites, there are built-in apps for Twitter and Facebook.  Not bad, but if you’re tempted to try to hack the Hero’s Android onto your G1, you probably should think twice about it…
