At random times when I click my Home button to wake up my iPhone it does not turn on. When I click it a second time the screen flashes then turns off again. I click it a third time and it comes on like normal. Is anyone else having this problem? It happens pretty sporadically and if I do recall correctly I believe it happened to my last iPhone 3g (This is my second one. My first one turned off by itself randomly) so I'm guessing it's something software related.
