Well its not possible to change OS in 5800, because all the OS have different architecture and run on different hardware configuration. So I do not think that it is possible to download the OS anywhere or change the version of the OS to anything else. Since Android is built with open linux kernel a linux based mobile phone like the motorokr, could easily change the OS, but all based on linux kernel. Just my 2 cents and good luck.
