Wireless Synching is Back with Windows Phone 7
"No doubt, one of the coolest features of Windows Phone 7 and the companion Zune Desktop software is the ability to sync wirelessly. For years we've had to endure tethering our devices to our computers, loose USB wires everywhere, etc. (Even more ironic is you remember wireless syncing in ActiveSync before they removed it)."
Microsoft may have taken WiFi synching out of ActiveSync a few years back, but it's been re-introduced on the back of the Zune desktop service - which is no surprise given that the Zune has been able to do a WiFi sync for a couple of years now. I didn't get a chance to test this with my Windows Phone 7 device - which, boo hoo, has now been sent back to Microsoft - but with my Zune HD is works really nicely so I'd expect it to be the same with Windows Phone 7. Read on for more on how this feature works, and how to set it up.
