The controversy over the iPhone 4's antenna issues continues to grow, particularly after Consumer Reports confirmed yesterday that every iPhone 4 suffers from signal attenuation when the phone is held with the lower left corner covered -- a report that we confirmed with results from our own custom signal metering app. At this point, there's no longer any question in our minds that the iPhone 4's antenna can be made to lose signal by holding it "wrong" -- and we definitely think it's more than a little silly that simply holding the phone in your left hand has been nicknamed the "death grip."

That said, however, it's not at all clear what the real-world effects of the antenna issue actually are for most people -- as we've repeatedly said, several iPhone 4s owned by the Engadget staff (including our review unit) have never experienced so much as a single dropped call, while others suffer from signal issues that results in lost calls and unresponsive data in a dramatic way. What's more, at this point Apple's sold well over two million iPhone 4s, and we simply haven't heard the sort of outcry from users that we'd normally hear if a product this high-profile and this popular had a showstopping defect. Honestly, it's puzzling -- we know that the phone has an antenna-related problem, but we're simply not able to say what that issue actually means for everyday users.
