Study into the implications of Smartphone operating system security UK sales (market share) of iPhones at January 2013 is estimated at 30.6 percent 35 making iOS the second most popular Smartphone platform By January 13 2013, 60 percent of iOS install base had updated their devices to latest version, iOS 6.0 36 , in less than a four month period Operating system updates This section details how Apple manages software updates for iOS devices. Apple will push out iOS updates for a variety of reasons including major functionality changes (full releases), minor functionality changes and emergency patches as a result of reported bugs or security vulnerabilities. Users will be notified that a new release is available usually via a message displayed on the iOS device. An example is shown below in figure 2.2.

Study into the implications of Smartphone operating system security Dependent on the policy adopted by a MNO, iOS users may be notified of a new release via email or even SMS text messaging. The role of MNOs in mobile operating system upgrades is discussed in more details in subsequent chapters. Apple has devised two ways in which a consumer can update the operating system of an iOS device. 1. Wirelessly using an FOTA update process from the device itself (available from iOS 5.0, released 12 October 2011) 2. Via Apple’s iTunes media application WIRELESS - OVER-THE-AIR (OTA) - IOS UPDATE PROCESS FOTA software updates for iOS devices have been available since iOS 5 was released during October 2011. This feature was part of Apple’s wireless and cloud strategy that untethered the device from a personal computer. Users no longer had to connect their iOS device to a personal computer for synching and operating system updates. Not all iOS updates are available as FOTA updates. See Appendix C for details on how this process currently works. APPLE ITUNES IOS UPDATE PROCESS Previous to the release of iOS 5.0 users had to physically connect their devices to Apple iTunes, via a personal computer, to allow system updates. This function is still available and is examined in full in Appendix D. Goode Intelligence © 2013 P a g e | 44 www.goodeintelligence.com
