While we were just talking about how MS Tag has passed the 2 billion mark for number of tags made, the question came up what about Windows Phone 7?

The reader is currently available on Windows Mobile, Android and even the iPhone but at launch, no client for Windows Phone 7 has been announced. Well, as you probably already read in the Tweet above, Microsoft has not only finished the Tag Reader app but it's being tested/approved as we speak, meaning it's just a matter of time before release.

Heck, there's even already source code to make a MS Tag generator. Looks like everything's covered here.
