It is so obvious the videos were doctored. Why didnt Steve himself lay out these handsets on the table at the press conference and do a live demo?
Because signal strength is very location dependent (plus a host of other factors including the weather, passing trucks, etc.)
I often get very different signal strengths from one side of a building to the other, and it varies from day to day.
And do you think all the other similar independent user videos on youtube are doctored as well? Why would Apple doctor a video if joe-blackberry owner didn't need to?
