The problem is, this Apple letter neatly sidesteps the point that while other phones are susceptible to signal attenuation when held at the bottom, the iPhone 4 is much more so -- especially if you “hold differentâ€ because you’re left handed. All the talk of a signal display flaw is a red herring (though true). That said, it's a testament to the “fiddly-nessâ€ of Android that this won't send customers flocking to it.
