Countless Apple iPhone users got more time in bed than they bargained for this weekend after the alarm clock malfunctioned yet again.
Widespread reports suggest that the problem is affecting single alarm settings, and that alarms have failed to go off on some iPhone 4 and earlier devices since 1 January.
"We're aware of an issue related to non-repeating alarms set for 1 or 2 January," Apple spokeswoman Natalie Harrison told Reuters in an email.
"Customers can set recurring alarms for those dates and all alarms will work properly beginning 3 January."
However, many iPhone users are complaining on Twitter that their alarm is still malfunctioning. One, Misty Albrecht, wrote today: "Going to dig out the ol' fashion alarm clock tonight. @iphone alarm has failed me yet again - at least I was only 5 min late today."
Another, CATrio, wrote: "Apple, it's Jan 3rd. Why is my #iPhone alarm still messed up? Please fix. Thanks."
The cause of the problem is still unclear, but the furore has echoes of a problem in November last year when the switch to GMT caused the recurring alarm system on iOS 4.1 devices to malfunction.
However, despite these glitches, the Apple device continues to outsell many of its rivals in the smartphone space.
The iPhone is outselling the Nokia N8 by six to one in Europe, for example, and eight iPhones are expected to be sold in 2011 for every N8, according to the latest research from Morgan Stanley.
