I decided to try out the Windows Phone 7 unlocked emulator image. It's pretty cool, you get to see a lot of things that are not available in the image that comes with the development tools. There's only one thing that makes it undesirable; you can't develop with it.
If you get the error "Error 1 a specified communication resource (port) is already in use by another application." and you've been using the unlocked emulator then you'll want to switch back to the image that came with the tools. I'm not quite sure what this is all about, but thought I would make this post for the sake of any one else that encounters it.
