While Jobs did admit this fact in his press conference, he mangled the stats to make the iPhone 4’s dropped call increase look minor. “The iPhone 4 drops less than one additional call per 100 than the 3GS,” he said. As Jobs sees it, that’s not a big rise in dropped calls. Yet that’s not an obvious conclusion. Last year, an AT&T spokesman told me that AT&T’s average iPhone dropped-call rate is 1 percent—in other words, the old iPhone dropped one call out of 100. If the iPhone 4 drops nearly one additional call out of 100, that could be close to a 2 percent dropped-call rate—or double the dropped-call rate of the old iPhone. That sounds a lot more serious, doesn’t it?
The number is 0,91% – http://daringfireball.net/linked/2010/07/21/att-antennagate
This article sums it up fine too http://daringfireball.net/2010/07/antennagate_bottom_line
Apple has fucked up the response and situation itself – the technical problem is not that critical, but the tone and approach is really wrong. Like the now infamous apple.com/antenna – just like 8 year old kids on the playground.
