Or you get sound so bad you can't understand the person at the other end, or
you lose the call altogether due to cell "shrinkage."

Possible, but capacity is almost never an issue, and there's no risk of being
dropped due to cell "shrinkage."

Only in theory. In practice GSM and CDMA use different codecs.
