How often, when you are on a call, take the phone from your head, while the other person is on the line and go on the internet? I did it maybe twice, and that's because I wasn't interested in what the other persons were saying.
the truth of the matter is that, people lived without it on the iPhone 2G, and people will of course live without it on Verizon. I mean look; Verizon has more subscribers than ATT (give or take, I might be wrong). these people don't ever complain about their not having data and voice together.
Don't mock. This was credited by the Wall Street Journal, and they do not just randomly publish uncredible sources, otherwise they wouldn't have a name.
