I can't agree with that blanket statement. AT&T might claim to have the least dropped calls, but you need a SIGNAL to make a call. No signal, no call, therefore no DROPPED call
I think the fallacy that everyone has is that because AT&T or Verizon is good/bad in ther particular neck of the woods, that automatically means that it's bad/good EVERYWHERE. That can't be further from the truth.
I could go on about my experience with Verizon and why I left them for Sprint and later AT&T, long before the iPhone was even announced. But it would be of little relevenace to anyone else in the other 49 states of the US. i don't know what Verizon or AT&T service is like in Nevada, or Arizona, or Minnesota, or many other places. So my experience is irrelevant to people there.
AT&T sucks for you? That's a shame, but that isn't my experience, and it may or may not be the experience of others. Verizon is excellent for you and CDMA is God's gift to cell phones? I'm happy for you, but again, it sure wasn't for me, and others may have different experiences.
This is why you should always follow two simple rules when choosing cell service:
1. Don't base your decision on what others say about the network. Each carrier has a trial period. Use it. And base your decision on YOUR experience, not what someone else tells you. If someone lives near you and travels around the same areas you do, then it's possible to make some general inferences, but I still wouldn't totally rely on their experience 100%.
2. Base your decisions on the network, not the phone. Even if it is the iPhone, what good is an iPhone if the network it's on doesn't cover you?
That said, I'm immensely happy with AT&T, and wish I had been on board much sooner. Your experience may vary.
There are two things no one can deny about Verizon though:
1. They like to cripple all their phones to a standard interface, and I doubt the iPhone we know and love now would have looked the same if Verizon had been allowed to get their grubby mits on it. Even the Blackberries have Verizon-specific schemes to them. And
2. Verizon DOES terminate any data users who, in their estimation, use
too much data.
