The point is only that AT&T fanboys are grasping at straws now that the Iphone is on a better network.
Straw 1: In many places AT&T has faster 3G speeds. Really, who cares as long as you have a MB/sec or more to your phone? Do you download DVDs to you phone? Upload CDs? Not likely - for the most part you're just hitting websites for a few hundred KB at most. 1 MB/sec or 1 GB/sec or 1 TB/sec is virtually the same user experience in that case.
Straw 2: Simultaneous voice + data. Who cares? Concoct your little usage scenarios - but in the end you'll realize that "I'll call you back" is more polite to the people on the call than expecting them to sit on hold while you surf. Get a life.
1 - I can get my NetFlix movies on my phone with no hesitation, movie plays very well.
2 - Very important to me if I'm on a call and it requires that check the web for information needed. "Hang on, I'll call you back" tells someone that they are not that important to you when they call you concerning information that you need to retrieve from the web.
I simply can't wait for Verizon's network to bog down under the weight of the iPhone and read the constant whining about how Verizon's network sucks...lol. Mark my words, it is going to happen and I will be there to smile and say "I told you so."
