Today's a great day for many iOS users looking to enjoy the biggest and most dramatic functional update to Apple's mobile operating system. iOS 8 started appearing as a free downloadable option on compatible iPhones, iPads and iPod Touches.
The update showd up just after 1 p.m. EST. On my iPhone 5s, the size of the download was 1.1GB and it says it would take around an hour to complete the download, possibly more for the whole update process. iOS 8 will be covered in a separate review but it is the most dramatic functional update to iOS and will bring some cool new functions like Continuity with OS X Yosemite, HealthKit and HomeKit integration plus various welcome add ons like third-party keyboards.
iOS 8 is compatible with iPhone 4s, iPhone 5, iPhone 5c, iPhone 5s, iPad 2, iPad 3, iPad 4, iPad Air, iPad mini, iPad mini with Retina display and the iPod touch 5th generation.
