At the stroke of midnight on January 1, 2011, the iPhone’s one-time alarm – but not the recurring alarm – ceased to work, according to technology news blog EnGadget . The glitch seemed to be affecting iPhones operation on iOS 4.0.2, iOS 4.1 and iOS 4.2.1.
Apple responded to EnGadget’s post about the glitch, offering a temporary fix to the issue and reassuring customers that the problem will be fixed soon.
The issue is related to non repeating alarms set for January 1 or 2. Customers can set recurring alarms for those dates and all alarms will work properly beginning January 3. Fortunately for some, the glitch came on New Year’s Day, a national holiday which this year also fell on a Saturday.
The issue is similar to a glitch on the iPhone in November of 2010 amongst European iPhone owners, whose alarms went off an hour late after daylight savings time. Similarly, in early October 2010, a bug affected Australian and New Zealand iPhone owners, whose alarms went off an hour early.
