Most of you are probably aware of the iPhone alarm clock
issue that started on January 1 of 2011. From what I’ve observed
and read the alarms won’t work if they are one time alarms. In
other words it an easy fix, if you just make your alarms recurring.
See photos below.
Hopefully apple will release a patch in the next
few days. If their alarms wake them up so they can work on it.
