"Go Go Gadget" (by Gnarls Barkley)

I finally got a passport - a "Global Passport" which enables us to use our cell phones not merely in Japan but overseas. Au, one of Japanese operators, finally released one, months behind the release of 905i series by its predominant competitor, NTT Docomo.

Now ready to takeoff

So far I've found three problems with Sony Ericsson's W61S, the only "global passport" model for au:
1. no mobile TV is available
2. no FM radio is available
3. this global roaming service won't cover S. Korea but 180 countries (or regions).
