With the percentage of them actually returned I have to wonder how many people that own an iPhone 4 are actually unhappy with it-- It seems the majority of people complaining now (post Apple's announcement to give out free bumbers/cases) don't actually have one.
I got to see and play with an iPhone 4 yesterday - the graphics are so clear compared to my 3G. Very impressive. My friend showed me what's considered to be the "death grip" on the phone. He likes it but has definitely noticed the difference in reception when employing the antenna death grip.
