No announcement yet that I can see, but several have told me via email that the Zune 4.7 PC software–which is compatible with Windows Phone and adds several other features–is now available.
The stunning site description reads:
The Zune PC Software allows users to enjoy Zune Marketplace content on their PC as well as load media content to Zune capable devices.
I’ll try to figure out if there any differences between the pre-release version I’ve been using and the final, but the hotel connection is slow so it might need to wait.
Thanks to everyone that wrote in about this.
