I don't intend for this to gloat at all - people generally express discontent rather than satisfaction online (and anywhere else), and I just wanted to let those worried about getting an iPhone 4 that mine is flawless. No yellow spots, absolutely no reception issues whatsoever (five bars everywhere in Vegas), and overall the thing's a beauty. I hope those of you with problematic phones get that remedied quickly, but I just wanted to make sure people understand that not every phone has a problem.
