iOS 8 is now here and available for download on most iPhones and iPads that were released in the past 3 years. As with every new version of software, there are some really great improvements and new features. But because there are so many new improvements, it's impossible to know of every new trick so here is a list of some cool features in iOS 8.

240fps Slo mo - If you have an iPhone 6 you can now shoot in even slower 240fps.
