The Isatphone Pro also has a built in GPS. In fact, it won't connect to the network until it's established a position, which can take some time, but then again you can easily send your position to someone, as seen below. It seems to me that once a marine docking station is real (soon, I'm told), it wouldn't be that hard to create an auto tracking app. Heck, there's already a firmware download tool on the Inmarsat site, along with the manuals. This isn't a smart phone but I suspect it's as close as a sat phone has ever come before. But I should test its performance more, especially in rain and fog, and in motion. It's an awful long way to those I4 sats, and I notice that when I tested the Iridium 9555 last summer, it worked in Gizmo's main cabin, where the Inmarsat phone doesn't seem willing. I have little doubt, though, that a new phase in the sat coms horse race is ON.
