For those curious, the Zune connector i.e. the sync/charge interface cable from the Microsoft Zune series, won't be used at all with Windows Phone 7 Series devices.

That's the good news, since said Zune connector is a little large and more than a little proprietary.

The bad news is that the WP7s chassis specifications don't require any specific sync/charge format, meaning OEMs who make our next-gen phones are free to use Mini-USB, Micro-USB or even their own proprietary format.

Now we hope OEMs have learned their lesson in regards to that last one, so we don't think we'll see many of those. Still, for those wanting a definitive decision with regards to Micro or Mini USB ... looks like Microsoft is going to let the old free market decide. [via Windows Phone Secrets]
