The announcement was made by Stephen Elop at the Nokia World event in Abu Dhabi, where the company unveiled long-rumored devices like the 6-inch Lumia 1520 and the Lumia 2520 Windows RT tablet, and it’s arguably the most important piece of info WP users have been waiting for.

There’s no specific launch date, and it remains to be seen if users of third-party client 6Tag will have any reason to switch to the official app, as the former offers a richer set of features than the latter, including multiple user accounts, unless Facebook decides to kill access to Instagram APIs for third-party apps.

However, most folks don’t want to make do with anything but the official client, so Instagram is a huge win for Windows Phone, and it takes away a major reason for consumers not choosing Windows Phone over Android or iOS. Other big name apps like Vine and Flipboard will follow soon after, so it looks like Microsoft’s OS is finally on its way to becoming a much more viable third ecosystem than it currently is.
