...using 3G data? I am going to get a Moto Milestone for ATT Gophone $60 unlimited voice/text. Since I will be using the Milestone in the US I wont get 3G and therefore I wont be able to use Google Maps Navigation App...is there an app that stores the maps either locally on the SD card or on the phone so I could use it as a navigation device even though I wont have 3G service? If so please share your thoughts on Android Nav apps pros and cons that store locally on the device itself as far as the apps go...thanks!
