So don't count on it.


The iPhone GPS is assisted GPS. That means that the cell network provides
an assist. If you are not connected to the cell network the GPS will take a
lot longer to get the signal.

Another oddity on the ship, the Nieuw Amsterdam was that I had no problem
recieving and sending text messages with my AT&T iPhone when connected to
Cellular at Sea. Tom had issues with his Verizon iPhone.


But my Verizon iPhone worked fine for texting on the HAL Veendam earlier
in the summer.

As the cell phone networks evolve, there seem to be lots of "glitches"...
