Scores of European iPhone owners showed up late to work Monday thanks to an iPhone alarm bug that gave them an extra hour of sleep. Apparently a bug in the iPhone's iOS 4.1 operating system resulted in alarms going off an hour late as Europe changed to daylight saving time.
Those who had their alarms adjusted to go off at a certain time every weekday got up an hour later than promised because of the bug, even though the iOS clock changed correctly over the weekend. The bug affected only those who had recurring alarms set on their iPhone prior to the Daylight Saving Time change.
Europeans were the second batch of iPhone users to be hit by this pesky iPhone bug, after users in Australia woke up an hour earlier than expected three weeks ago, when they had their clocks go an hour forward.
Apple said it is aware of the problem in early October, and that it has already developed a fix, but the solution will be available only with a future software update (which could be iOS 4.2 expected sometime in November).
Meanwhile, to address the recurring alarm problem on iOS 4.1, all you need to do is delete any recurring alarms you might have after the clocks go back an hour on Sunday, November 7, and re-enter them. Alternatively, you can adjust the recurring alarms times to an hour early, or turn the alarms off before the hour change, and reactivate them after the daylight savings.
U.S. iPhone users, consider yourselves warned: on November 7 when we set our clocks back an hour for Daylight Saving Time. iPhone owners might want to rely on their trusted bedside alarm clock and leave the iPhone for making calls.
