Instagram may have missed the initial iOS 7 update run last week, but the retooled iPhone app is good to go now. Version 4.2, available for download today, brings design tweaks that mesh better with the latest iOS, with a slightly simpler interface and rounded profile pictures in the feed. Additionally, photos and video are a bit larger, and the resolution has been increased as well, enabling a better viewing experience overall. Instagram for iOS 7 can be yours right now. You'll find the download at the source link below.
