The tag windows-phone-7 should be retagged windows-phone. While there are a few more instances including the
7 bit, the questions listed all apply to every current version of Windows Phone, including the planned release, "Mango".
Therefore, the tag should refer generally to the platform, rather than a single specific instance of the OS.
However, I lack the reputation in either tag to make the suggestion. :(
Can someone do that?
