Using an American iPad in Japan
I am looking a buying an iPad, but in October I'll be moving to Japan for a 1 year study abroad program. I know that US iPads aren't carrier locked (while Japanese ones are). If I go ahead and purchase one in the US, will I be able to have 3G connectivity in Japan? Softbank doesn't seem to offer much info on the subject, so I'm wondering if I will be able to use their data service without buying the iPad from them. I don't want a Japanese one because then it will be useless when I return to the states.
Thanks!
