Look I like the show Mythbusters, but I think one of its co-hosts, Adam Savage (the normal looking one) is whining.
Seems he went to Canada and spent several hours surfing the Internet on his phone for which he has an AT&T service plan that evidently charges more for international coverage, just like yours and mine. And so he got a bill for $11,000.
Yeah, I know, I have heard a comedy routine where comic Kathleen Madigan complains about the same thing, having gone to Canada and used her cell phone and gotten a big bill, because - oh mah Gawd! - they discover it is NOT the United States.
Tough titties (and since Canada is officially bilingual, mammaries durs). If you were in Hong Kong, you'd be cognizant of the fact that you are in a foreign country and watch the cell phone use, or find some equivalent. And if you have a popular cable TV show, maybe they was some reasearch you were doing while texting and write the damn bill off.
