This is a serious question? I mean, given how Steve and Apple did react?
Ok, the easy part, I wouldn't have sent an email telling someone the problem was the way he handled the phone and to handle it differently, aka you're holding it wrong.
I wouldn't have feigned an "oh my gosh! we've used a wrong bar formula all along! you can't believe how surprised we are!" response with the pretense that "cosmetics" was the only issue and it would be solved soon via a patch.
Good for starters?
Yup, a good start. And #3 would be either:
"we understand there are some unconfirmed reports and we are looking into it"
As much as I think Apple made a mistake in the design (physical contact with an antenna affects its performance - end of story), they made an even bigger blunder with their arrogant and clumbsy responses to the complaints.
say nothing more until you've determined a course of action
