How do I authorize a Windows Phone 7 device to allow for visual studio to deploy to it?

I've registered as an app developer with the Micros开发者_Go百科oft store but I'm at a loss, under devices I'm told that I need to authorize devices to use for app development but it says: "Adding additional devices must be accomplished through Visual Studio" with no added information. I tried using the 'XNA Game Studio Device Center' to add the device but it only has Zune and Xbox 360 listed, clicking on Zune doesn't help as it says no Zune device was found (since it's a windows phone 7 device I suppose that's to be expected).

So how do I add a device so I can deploy to it through visual studio?

Using the live id for your active marketplace subscription, enter that and your password into Windows Phone Developer Registration in the start menu.

You can only register a device using windows phone developer registration program once you have completed GEO Trust verification. On your Windows Phone dash board on App Hub you'll see that you must complete verification before your able to register a device.
