2011 Starts With a Glitch for Some iPhone Users

Many iPhone customers had some explaining to do after they overslept to start the new year, due to a glitch in the gadget's alarm clock feature.

Users who set their iPhone alarm for a single wake-up rather than recurring use found the alarm didn't go off with the year's arrival, Apple spokeswoman Natalie Harrison said Sunday.

A fix is in the works, and all iPhone alarms will work properly starting Monday, she said.

The glitch affects iPhones using Apple's latest iOS 4.0 operating system.

Online postings on blogs and social media sites described people being late for work, church services and other appointments on Saturday and Sunday because of the problem.
