Microsoft pushed out an update to the Zune desktop player, indicating that an update could be on it’s way to WP7 phones.

The version number in the Zune About screen doesn’t change, staying at 4.7.1404.0, so it would appear this does nothing but allow Windows Phone 7 updates. What is visible if you poke around deep enough is ZuneWmdu.dll and ZuneWmduResources.dll are updated and those two files are known to be necessary for the WP7 update process.

Would this update also indicate a support for upcoming Nokia phones (if they marry Microsoft to run WP7 ?)
