Software Update Prevents iPhones From Making Calls Apple quickly pulls iOS 8.01 amid complaints By John Johnson, Newser Staff Posted Sep 24, 2014 3:34 PM CDT 45 comments Comments Apple CEO Tim Cook speaks about iOS 8 in San Francisco on June 2. (AP Photo/Jeff Chiu) (Newser) – Apple had to quickly yank an update to its mobile software today after the upgrade caused more problems than it was supposed to fix, reports the Verge. The company released iOS 8.01 this afternoon, hoping to get rid of widely reported bugs with iOS 8. But about an hour later, Apple reeled it back in and said it was "actively investigating" reports of problems. Among them: Users could no longer make calls with their iPhones or use TouchID to unlock their devices, reports the Wall Street Journal. The unlucky users who quickly pounced on 8.01 can revert back to the still-buggy-but-less-buggy iOS 8, and CNET has a how-to here.
