I'm also going to be jumping my Sprint family to AT&T. They appear to have dumped a ton of money into Phoenix so I believe they've probably gone from okay to really good or something. Unlimited data with Sprint becomes less appealing when you realize how slow it is.
And I seriously question all the bad press AT&T gets. It just doesn't add up, if they are as bad as all the "studies" claim then why aren't they dying as a wireless company? I'm guessing the negativity is more focused than most people think. They might be really really bad in only certain areas (like NY) and also possibly only with certain devices (iphone saturation), but be decent to good everywhere else. Because some of those places are really dense though, or there are so many iphone users, that might be skewing the results a ton. The sheer amount of negative press just doesn't add up for the nations second largest carrier. I'd expect them to be in third to last place. Just a thought.
