Not sure if this is an actual Easter Egg or not, or just my iPhone doing strange things on this day of bad luck, but when i woke up this morning, the lock screen on my phone repoted the date as Friday 13th May, yet for all my trying I couldnt get the calendar icon to actually update to the correct date.
Seems there might be a good chance of some supersticious code developers working within Apples walls :)
