Unfortunately, you're misunderstanding what Jobs said. They said it drops ~1 call per hundred than the 3GS, not 1 percentage point more. That's a huge difference. It means that if the 3GS drops 1% of calls, the iPhone 4 drops 1.01% of calls.
What? I don't really get my head around your math or I just misunderstand what you are trying to say. 1 call per 100 calls means one percentage point.
Jobs said: "One or less additional dropped call per hundred calls". I don't know how I should parse this to be "one percent more dropped calls than 3GS".
Actually I believe Geee is correct and YOU are misunderstanding Jobs. Here's the actual quote: "...iPhone 4 drops more calls than the 3GS. But how many more calls per hundred does it drop?...The iPhone 4 drops less than ONE call per hundred than the 3GS.” To me this reads clearly that were one to make 100 calls on each device, the iPhone 4 would drop between 0 and 1 more calls than the 3gs which is consistent with Geee's interpretation.
It looks like lots of people just read live blogs and second hand accounts. It's shocking to see how easily and quickly the facts get mutated these days.
Just to show I'm somewhat unbiased on the issue -- if we want to question Apple's data why did they show AT&T store returns and not Apple Store returns?
