You'd think Instagram, with its massive popularity and perfect price tag, would've been top of the Apple charts at least once by now, but according to the company, it's only done it for the first time tonight. Reaching the pinnacle of the iOS free apps list, Instagram seems to have found new momentum in the wake of its billion-dollar acquisition by Facebook.

There was a quite unpleasant backlash among Instagram's iOS users when the Android version of the app was released — with some claiming they'll stop using the photo-altering and sharing service due to the "dilution" of quality that would result from letting in the great unwashed of Android — but as it turns out, those misguided souls were exactly the minority we thought them to be. The hype of the Facebook acquisition and the expanded community resulting from being on Android have apparently helped breathe new life into Instagram's growth.
