You're joking, right? You do understand that the whole point of a smartphone is to easily get information that would otherwise require a desktop OS, but goes straight to your pocket wherever you are. Thus, wherever you are indicates that you could be without a laptop. Or are you someone that carries a laptop with you everywhere you go and thus don't understand why people buy smartphones?
That's what happened with my iPhone 4, and why I decided it was time to replace it. I got it right at launch, and I really was hard on it, though. Going to the 4s was a good compromise, because they are cheap right now LOL
My hubby had his iPhone 4 in a Griffin Defender case and his home button worked just fine.
LOVE the back button! I want one! And an LED notification...
