Many people already turn to satellite phones when they're at sea or in other far-off places, but a new device from Iridium takes a satellite signal and turns it into a Wi-Fi hotspot for your existing mobile devices.

The Iridium Go! is a lot like a portable hotspot device that you might pick up at your local wireless store. Only instead of picking up a local 4G signal to send to your tablet or laptop, it supplies some of those devices with the same data that you'd get from a satellite phone. The downside is that this data is going to be ridiculously slow (Iridium tells me "up to 2.4 kbps"). But the upside is that you'll have a connection to the outside world no matter where you are.
