We leave for Florence Italy for 2 weeks. We should have a working cell phone with us, and I'd like to have a GPS-something I can use to navigate on a bicycle (and car). I believe my Droid I will not work, even if unlocked and supplied with a European SIM card. Right? Verizon will give us a phone, but it costs $1.29 per minute and something like $20 per MB of Internet access. They say it has some navigation capabilities, but not Google maps. I can rent a Eurpoean-ready phone with much cheaper talk minutes for not too much money, but it won't have GPS and map capabilities. I can't find anyone that rents Droids or such. I could buy a portable GPS navigation system in the US that could be loaded with Italy maps, but once the trip was over it would duplicate capabilities of the Droid. Any thoughts or suggestions would be most welcome!
