Well this came from nowhere.  I guess they do not want to give iPhone users any more reason to get another iPhone instead of a Windows phone, but Office is Microsoft’s biggest profit product, and they know they need to move to the cloud with 360, so they bit the bullet and released an iPhone app.  Keep in mind this is iPhone only, 4 and up, iOS6.1 and up. No word on the ipad yet, but it will work on it.  Just in iPhone mode.  Check out the video below.

Here is the blog release from Microsoft.
