Numerous reports are coming in about a couple major problems with the new iPhone 4:
"Apple iPhone 4 problems crop up: screen discoloration, reception issues" VentureBeat
"IPhone 4 users reporting reception problems when holding phone" SF Chronicle
"Some iPhone 4 owners report discolored screens" CNET
After reading these various stories, I think there is some validity to my friend's analysis that the dropped calls and bad reception isn't all AT&T's fault. He believes that it's also the issues with the iPhone itself. Whose ever fault it is, I'm so tired of having full bars on my iPhone and still getting poor reception that I'm switching back to Verizon when my contract expires.
