The list on the web site is not even up-to-date, but it can change at any time. Sony is more than happy to Playstation-certify additional Android devices, if they meet the criteria. The reason that there isn't more of them is that it isn't a priority for most phone models that aren't made by Sony. Android already plays lots of games, and there are no Playstation Mobile exclusives that are in high demand yet.
Is there a more up to date list somewhere? It would be nice to know all phones that have PSM if that list isn't up to date.
