Filed under: iPhoneI upgraded my iPhone 4 to iOS 4.0.1 and, big surprise (not), it still can't make phone calls if I'm holding the thing in my left hand using the kung fu grip of doom (i.e. the normal way I hold a phone). And, unsurprisingly, my 3GS still can make phone calls with the same grip in the same location.
I ran the Strength App, which we've discussed in previous posts about the iPhone 4 antenna issue. It is now showing a more nuanced level of how bad my home reception really is, but the bottom line remains the same.
