Surprising all Apple focused Windows Phone 7 owners (myself included) with native support for their new platform, Microsoft has had their connector software that allows seamless synchronization between WP7 devices and OS X in beta since October '10. It has now gone gold.
Unfortunately, there is still no Zune software available or that has been rumored to be in active development, which would be welcomed with open arms. There are no reportable features that have been added to the Connector, only fixes and enhancements. Still allowing media synchronization with iTunes & iPhoto and allowing WP7 device firmware updates we don't truly have grounds to grumble.
Head on over to the App Store to download the latest installment for free. Should you have it already and the store is not reporting an update is available, simply drag the Windows Phone 7 Connector icon from your applications list to the trash can and then install from the App Store.
