I'm leaving for Havana, Cuba on Monday. GPS units are illegal to bring into the country. I do have an Iphone with the Groundspeak app loaded. My understanding is that US cell phones won't work (and I probably wouldn't want to pay the data fee anyway). So the question is this: will the gps on my cellphone work if I have the send/receive data off. I'm sure this geocaching 101 at this point, I just want to make sure. There is one cache near my hotel that I think I can find without a gps, but there are several more available if...... Thanks Joel CacheRcheck
