Steve Jobs today showed that other phones can drop bars by using the death grip. However, I can get my Iphone 4 to drop with a simple touch someone show me a video of another phone doing this? Why is this not considered a simple design flaw? Do other phones do this?

Ryan from gdgt: You showed people almost covering the entire phone in their hand, but on the iPhone 4 it can happen with just a touch. Can you explain that difference?
Bob: When you touch the phone, you put yourself between the signal and your phone, so when you touch that spot you can attenuate the signal, and if you grip it with your whole hand, you can attenuate it even more. We don't build phones with an antenna on top...
Hmm, that didn't really sound like an answer to us.
