You probably won't find that much information about this topic, well not useful information anyways. As far as i know, the tour doesn't work on a lot of android phones. The ones we have tested on are, Desire and wildfire. The reseller where we got the headphones from claims that the tour works with Nexus one, however i have not tested it. It would be interesting to know if other brands work...
P.s my beats studio works on all android phones with 3.5mm plug... and i have no idea why as physically, the plug is exactly the same.
