That's not been shown. All that was shown was that the number of bars dropped. What does that mean for the other phones? How much signal loss? Pretty pictures are pretty, but not to substantive...
Admit it, you're WRONG!
About what? That the iPhone 4 has antenna problems? Apple just confirmed my statement... Why else would Steve Jobs admit the iPhone 4 drops more calls than the 3GS, needs an antenna cover (the bumper), and is being "fixed" by September 30th?
If I'm wrong about this, then so is Apple...
The iPhone 4 is not experiencing MASS RETURNS or COMPLAINTS.
Their mass complaints are coming from non-users such as YOU.
