How well do blackberries work in Taiwan?

[psidriven]

Visiting my friend in Taiwan for a week next month and bringing my company blackberrry with me. Company pays for international data but not calls. So I can get a phone from my local friend for calls, but wondering if I can still use the blackberry for non-call stuff like maps, internet, etc. I remember something about RIM not having an Asian interface or something like that.

LMK if anybody wants something from the SF Bay area. Trying to bring a Zachary's pizza as a surprise present for my friends family, haha.
