A friend of mine upgraded the OS on his iPhone a while back. I kept getting called from his phone and when I answered, there was nobody there. The first couple of times, I though it was a pocket dial, the next several started making me wonder why he thought it was funny.
Veronica and I were going to get her nephews and take them to the farmer's market. On the way, we stopped at his house to ask him to stop calling. He met us outside with his iPhone in hand and proceeded to state that he couldn't get it to stop without turning off the phone. Every time he turned it on, it would call the last number dialed, (which was mine), before he could do anything else.
Apple isn't as perfect as their reputation would make one believe...
