FutureLawyer has an interesting take on the iPhone and Verizon:
I have a modest proposal. All current AT&T customers should stay with AT&T so that you will have more bandwidth for your iPhone calls. Verizon is not the network you are looking for. Hey, you have been telling us for some time that AT&T is a faster network, and that you can make iPhone calls and browse the web simultaneously, and that you cover more people. So, if AT&T is such a superior network, why leave it? Stay where you are. NOMN (Not On My Network).
