I searched but couldn't find a main resource on how people are using their iPhones/Android phones for a GPS alternative for adventure riding. I think a sticky on this topic would be very helpful since this is a technology that is going to advance or evolve a lot quicker than the stand alone units. With tank bags that have phone/gps locations or bar mounts for phones are making it much easier to use that phone that you always have on you anyways. The issue is keeping up with the newest apps or topographical resources to replace a stand alone unit. Is there anything on here already? If not let's do this! I downloaded Galileo today ($3.99) and I'm going to play with this for while first.
