After an official iOS 8 2 days ago, Fiksu statistics reveal that the adoption rate of the OS is still very low; far below the rate of adoption for IOS and IOS 6 7 8 iOS itself is only compatible with the iPhone 4s to the top and also the file size is quite large, so it can be understood if the user chooses not to immediately upgrade early release because they require more time to save old files.

For fans of the jailbreak, iOS release 8 yesterday also clearly be a new dilemma: if they hold strong to use jailbreak of iOS 7.1.2 on iPhone & iPad that they use and missed a wide range of the latest features in iOS 8, or immediately install it in order to feel iOS 8 and eventually lose their jailbreak, given after a user installs iOS 8, then they will not restore to iOS 7.1.2 software.
