Apple apologises for iOS 8 update bug blocks calls

Apple has apologised after an update to its mobile operating system left some owners of its new iPhones unable to make or receive calls.

Users who had installed iOS 8.0.1 on the iPhone 6 models also complained it had caused problems for the handsets' Touch ID fingerprint facility.

The update had been released less than a week after the phones had gone on sale in order to fix other issues.
