SAN FRANCISCO — Apple's newest iPhones ran into some glitches Wednesday after users complained that a new software update blocked their calls, and a video circulated to suggest that the larger of the two new models is vulnerable to bending.

Apple said it would stop providing the software update, which it began distributing Wednesday morning to fix several issues in last week's iOS 8 operating system for iPhones and iPads.

The decision to pull the update came after some people complained on Twitter and in Apple user chat rooms that the update, dubbed iOS 8.0.1, rendered their phones unable to make calls and caused problems with a feature that lets people unlock their phones with their fingerprint.

Apple said Wednesday it was investigating the reports and would issue advice to users “as quickly as we can.” Users are still able to the upgrade older phones to last week's version of iOS 8, which Apple said has already been downloaded to nearly half of all iOS devices.

NEW YORK — NutraSweet says it will no longer make the artificial sweetener aspartame as a result of foreign competition.The privately held company said Wednesday it expects to shut down a major portion of a plant that employs about 210 workers, including contractors, by year-end as a result. That will leave it with only about 10 to 20 employees to focus on its two other smaller sweeteners.Aspartame is more commonly known as the ingredient used in Equal.
