Certainly you’ve heard of “Antennagate” by now. It’s all the hype surrounding the fatal flaw in the iPhone 4′s genius new antenna design that causes it to lose quite a bit of signal strength when you hold the phone. I haven’t tried it myself, but I have tried holding a couple of my other phones in a way that would consistently make them lose signal strength.
Interesting fact #1: No matter what I do, I cannot get the iPhone 3GS to lose signal strenth. Even if I completely surround the phone with both of my hands.
Interesting fact #2: I can cause my HTC EVO 4G to lose signal strength consistently, by holding it in a way that I would never actually hold it. Holding it in this position also disables the camera. Good thing there’s a backup camera up front
