It was only sensible to go with AT&T because AT&T waved a giant stack of cash and it smelled good to Apple and its shareholders. The other choices were sensible, just not as lucrative.

I don't begrudge them for pursuing the best financial deal possible, but you can't then say they had no other choices because of technologies. It was a financial decision, not a technological decision, and if Verizon were coughing up $400 per phone (or whatever it is) the iPhone would be CDMA-only in the US and GSM everywhere else.
