mobile coverage - east coast
I use SprintPCS along with the connection to my laptop. It worked great while traveling out through the Keys. Coverage of course, seems to follow Interstate Highways so I would have to imagine that it is good most the way up the east coast. I heard that Sprint was expanding their service to Puerto Rico and the US Virgin Islands with the Eastern Caribbean soon to follow. Unfortunately nothing seems to work well in the Bahamas. The locals use their VHF''s. The best way to go is with pocketmail there.
