To me it seems as if the people complaining the most are those that have never even touched an iphone 4... and I'm curious to see how widespread and serious the problems really are. I won't deny that I can replicate the signal issue... however for me it's such an unnatural grip on the phone to actually cover that spot. The yellow spots fade away. All phones break if you drop them. Get a case if you're too worried. Anyways... I just want only iphone 4 owners to vote... and comment if you have any real issues with the phone that REALLY affect you. Not just that you can replicate by doing things you wouldn't normally do anyways.
