iPhone users worldwide have reported over the New Year’s Eve weekend that iOS continues to be plagued by alarm clock bugs, this time affecting non-recurring alarms.

Reminiscent to the daylight savings bug reported by iPhone users worldwide last year, this error appears to be identical at first, only it does not affect recurring alarm clocks (as with the daylight savings bug), but non-recurring alarms.

In other words, those who set their phones to ring just for January 1st, 2011 would not be woken up. To avoid this, users had to set a recurring alarm, by tapping repeat in order to select the days they wanted the alarm to ring on.

After running a few tests to determine what scenarios the alarm bug involves, which iOS versions etc., 9to5mac learned that the issue fixes itself on January 3rd.

The tests were presumably carried out on a handset running iOS 4.2.1, the latest version of Apple’s mobile operating system.

An iPhone user going by the name of Aaron F. could confirm that iOS 4.1 and iOS 4.0.2 were also affected, the report adds.

iOS 3.x devices seem to remain unaffected by the bug.

Last month, The Guardian leaked details that indicated the planned release of iOS 4.3 at a December 9 Apple event.

Also last year, anonymous sources were telling MacStories that Apple had planned to release iOS 4.3 in mid-December, primarily aiming to enable users to subscribe to News Corp's alleged tablet-only newspaper, The Daily.

With December 2010 now behind us, Apple is believed to prepare the release of an iOS software update (not necessarily iOS 4.3, but potentially an iOS 4.2.2) for January.

As with all iOS releases, the upcoming update will deliver new features and fixes for all known bugs.

Luckily for Apple, January 3rd came and fixed one for them.
