If that's your tipping point, more power to you....but I usually prefer to pay attention to the people who I'm talking to.

I know, you or someone else, might need information from the web or an e-mail that's pertinent to the conversation, but there are many more reasons I would not use an iPhone on AT&T. For starters, if you can't get an effing signal in the first place, you don't have to worry about talking and browsing simultaneously.
