What they could have done, is said "on the iPhone 4, we are experiencing only a 3% increase in dropped calls vs iPhone3". They are using numbers to obfuscate the issue.
On the AppleCare numbers, they could have said "Out of all the calls we got on iPhone 4, only 1% of the calls were about the reception."
Notice that they cherry picked numbers, and presented in a way that sounds great, but have no real meaning. So what if only .55% of people called AppleCare about this issue? If that is 80% of their call volume, then it is a real problem affecting users.
From what I read, they didn't admit they had an issue. The tried to prove there isn't an Apple specific issue, and gave inconclusive numbers to try to bull**** their way through.
I don't want them to do anything. I want people who listens to them to think about what they heard, and that applies not only to a new conference, but also to what anyone says in a public forum.
