I had a week off work over Xmas and my first day back was yesterday (Sunday), I was late getting up because I had apparently slept through my alarm.
Now I had had a few ales on Saturday night but was still amazed that I hadn't heard my alarm.
Seems there was issues with all Iphones in Australia, I realise not many folks would have been working on a Sunday but was wondering did anyone else have this problem (and maybe miss something real important like an early surf session etc).
