I have a wifi 16GB iPad and an iPhone 4 and Macbook Pro.
Sort of kicking myself for not getting the 3G iPad as I want to use it for marine navigation. Can anyone tell me what the range of the 3G GPS chip is and its area of operation? I know it will work without a phone connection from following other posts, but how far from shore will it work? Will it work in US/Caribbean and Europe for instance? Can't find this info in user guide.
