Surf the web while flying?

I usually don't read the posts about electronics, so please excuse my
ignorance if this subject has been visited previously. I'm wondering if
there is a device similar to a handheld GPS receiver (same size, portable
antenna that suction cups to a window, battery powered) that I can use to
surf the web while cruising at the flight levels. The new cellphones won't
work at altitude. If there is a device like I desire, will it work over the
ocean or only over the continental US?

Thanks,
D.
