The folks over at Nordkapp have released a Windows Phone 7 Cheat Sheet to help developers with their app design. It is based on Microsoft's Design Guideline documents so it doesn't stray too far from the source while it offers additional input that could help you out. However to you non-developer folks - you can have a look at it anyway to see what goes into the design process of developing an app for WP7. Even iOS/Android app developers might learn a thing or two from it.
Head over to the Nordkapp blog to check out the designers cheat sheet.
