I am using the Yahoo! weather service. If I send it a zipcode that doesn't resolve to a city location, it does return a chunk of error XML - so I am using that as my validation now. I put up an alert notifying that the supplied zipcode doesn't work so another can be tried. It's not as nice as supplying a city name and choosing from a list of matches, but it works well enough I guess. I thought about using another service to validate a zipcode before sending it - but since I get the error supplied to me I can skip that extra step.
I appreciate all of the feedback I've gotten on this - it's been very helpful.
