I just posted this to my Windows Phone Secrets blog, but I thought it would be interesting to SuperSite readers as well:

I received word back from Microsoft on my connector query. It turns out that Windows Phones will not use the Zune connector as some had hoped. Indeed, the otherwise rigid Windows Phone 7 Series hardware specification does not stipulate a physical interface of any kind, even mini-USB. So device makers are free to implement their own device-to-PC/charging solutions, and we’ll likely see a mix of mini-USB, micro-USB, and even (shame) proprietary connectors on Windows Phones.
