Looks like the CDMA iPhone isn't going to work with every iPhone 4 case, due to the change in the mute switch.

For now, I'm sticking with AT&T. Verizon doesn't service where my parents live, and I currently share a family plan with them to keep monthly costs down. I've also never been hit with roaming charges while in the US, but I've heard this is still possible on Verizon when out in the middle of nowhere. I'm hoping enough people will leave AT&T to make the network run a little better, as I've noticed data congestion issues here in southern California.

Hopefully this will lead to some good price competition (though I doubt it will), and once LTE rolls out, the ability to switch carriers without switching phones.
