after installing iOS 8.0.1 it seems that some iPhone terminals or iPad tablets, including mine iPhone 6 si 6 iPhone Plus, refuses to connect to the network, and it seems that the problem is quite widespread. Moreover, the Touch ID system refuses to work in the case of certain terminals, touching the Home button hiding the slider for unlocking the terminals, in the absence of a Touch ID to activate.
Practically after installation iOS 8.0.1 you will no longer be able to use the telephony function of some iPhone terminals and it is not known yet if it is only about the new iPhone 6 si 6 iPhone Plus, or other terminals are also affected. Considering that Apple is still signing iOS 8, you can quickly restore to that version of the operating system, but this also requires restoring a backup with your data.
