We take a lot of iOS screenshots here at Redmond Pie. Whether we are reviewing an app or we just want a unique image to accompany a post, we are constantly taking screenshots.
The public release of iOS 5 in October 2011 brought a number of new and exciting features for the average consumer as well as iOS developers. A number of these new features are well documented and are heavily featured whenever iOS 5 or the iPhone 4S are mentioned and include things like the Siri, iCloud integration and the new Notification Center. iCloud is more often that not, referred to as a feature in its own right, which is generally not a problem, but it is worth noting that iCloud is effectively a wrapper for a number of new additions to the iOS platform.
The reason why many people jailbreak their iPhones, iPads and iPod touches is to add, or sometimes even remove, certain functionality. Some even just want to alter how one particular feature works, tweaking something about it that makes it infinitely more useful than Apple had ever intended.
