Are there any good pocket or hand held electronic translators? (From Chinese to English)
Should I purchase one from the states or from china?

Of course, wait until you arrive in Kunming, there are hundreds to choose from, and they're less expensive.

Thank You! Are there any for handheld PDA cell phones like a Blackberry or PALM? Or are there just seperate units?

sure. electronic things are everywhere in the world. do not forget most of them are made in china:)
