While we know a lot of developer units for Windows Phone 7 would be sent out in the last few weeks, we didn't know exactly how many.

Turns out it's just above 3,000. That's a lot of non-production prototypes if you think about it. Then again, it's a drop in the bucket in terms of developers who still want a device and who are needed to beat back the Android craze.

Cyber Monday may be over but these Cyber Week deals are still alive

The number comes by looking at the official Windows Phone 7 Facebook app that comes with the device. The logic being that 3,000+ users have installed this app on their phones, hence the correlation.

Then there's probably the ten or twelve people like myself who don't have Facebook, natch. So more like 3,088.
