With Twikini seemingly out of the picture and Windows Live not resolving their Twitter API issue, Windows Phone 7 is a little behind on the Twitter front (though lets not forget about Seesmic).

TheUnwired.net has an interesting theory, albeit lacking hard evidence, that Microsoft may be providing some type of native Twitter support after all.

This is one of those we could seriously believe Microsoft doing before the 1.0 official launch and think it is certainly a possibility.

The story goes like this: Michael Klucher, Microsoft's Lead Program Manger of the XNA Development Platform, showed off a few pictures of some Windows Phone 7 games and tweeted them to his account. The photos's EXIF data confirm a Samsung camera had taken presumably from those Samsung developer units.

The interesting part comes from the Twitter client information, which every Tweet marks to ID the originating software e.g. "Seesmic" or "Twikini". In this case, it says "To be named later" which is...well certainly odd and interesting. Even more so, it links back to https://www.windowscentral.com/e?link=https%3A%2F%2Fmicrosoft.msafflnk.net%2Fc%2F159229%2F433017%2F7593%3FsubId1%3DUUwpUdUnU1245%26subId2%3Ddwp%26url%3Dhttp%253A%252F%252Fwww.microsoft.com%252Fen-us%252F&token=MXtVvLoF (dun dun dun!)

The theory goes that Kuchner is using a beta version of a native Twitter app for Windows Phone 7. Ta-da!

Like we said, totally plausible and we hope, very true, but at this point...just lots of circumstantial evidence. Read more at The Unwired.net.
