During Nokia’s Lumia tablet and smartphone event in Abu Dhabi on Tuesday, Instagram CEO and co-founder Kevin Systrom revealed the app most Windows Phone users have been eagerly waiting for is finally coming. When? An exact date wasn’t given; all we know is Instagram will arrive in the “coming weeks,” so it’s safe to say it will be here by the end of the year. “Our ultimate goal is to bring Instagram to everyone who wants to use it,” Systrom announced. “We’re looking forward to watching the Windows Phone community use Instagram to capture and share beautiful moments in the coming weeks.” Many consider Instagram to be the most important app that Windows Phone still doesn’t have. Now that we know Facebook gave the green light for Instagram to dedicate resources to Windows Phone, Microsoft’s mobile platform has received a huge blessing.
