A bug in Apple's iOS4 meant that Europeans got an unexpected and for most an unwanted extra hour in bed following the end of Daylight Saving Time.
The bug meant that while the clock automatically updated, flipping back an hour, the alarm settings didn't update.
This bug's not new. Folks relying on iPhones to wake them up in New Zealand and Australia last month were woken up an hour early after their clocks went forward an hour. Apple it seems has done nothing in the interim to fix this bug. Apple should be embarassed that its flagship product is afflicted by such a remedial flaw and that it has failed to fix this known issue.
DST ends in the US on the night of November 7th, so if Apple hasn't released an update by then, those using iPhones as alarm clocks had better have a backup plan in place.
This bug can be avoided by using one-off alarms rather than a regular wake-up alarm. Not convenient, but better than waking up an hour late.
