This is such a misleading statistic, because it assumes that every single person who experiences the problem is going to immediately call Apple to complain, and that is simply not true. I can make the problem happen for me by using the grip of death, but I never called Apple to complain. And I'm sure there are many, many more people like me.
I think a much more telling statistic would be, out of the sum total of calls received regarding the iPhone 4, what percentage of those calls were about the antenna problem?
And the ending made no sense at all taken with the departure of Kate, Sawyer and Clair on the plane. How does Kate end up at the funeral dead if she managed to fly off the island alive? Why even bother to get that group to the plane, if it is meaningless if they reached it or not?
For all we know, Kate lived to an old age, then died and went to the "purgatory" funeral in the altiverse. Remember, Christian told Jack that some of the people at the funeral had died before him, and some had died long after him. Kate could very well have been one of those who died long after Jack. Since there was no "now" in the altiverse (as explained by Christian), time was irrelevant there and all the people who had died at various different times were able to gather together there before moving on to the afterlife.
