Anyone who has an iPhone or iPod touch and has interest in snapping photographs or getting involved in social circles will more than likely be familiar with Instagram. When the app was first released for the iPhone, it took the world by storm as it was one of the first of its kind which allowed filters to be applied to photographs which would in turn be uploaded and shared with the rapidly expanding Instagram network. Things have changed a bit since then thanks to Facebook’s takeover and numerous app revisions, but it is still one of the most popular downloads on the iOS App Store.
