Some clever hackers have somehow managed to install the Android OS onto an Omnia i900. Don't get too excited, though, as this is the first build, which is very glitchy and unfunctional. Still, if you feel like testing it, you can download the latest software build here.
Also if you yourself are a developer, who can provide a working build, you can win... lets see... $476+ atm. For more details visit AndroidOmnia.com.
