Going on to Japan for a short vacation & I'd like to be able to use my N900 there. Anyone know if the N900 can be used there? All I really need is data.

The only option that looks viable is this http://www.bmobile.ne.jp/english/3g.html which is a USB 3g modem precharged with 150 hours of usage time. I'm assuming it contains a sim that can be used in the N900? If this works can this be resold too since 150 hours is way more then I plan to use & with the device costing $400.

If that doesn't work is there a rental phone with reasonable data rates that could possibly be tethered to the N900?
