[citation][nom]warezme[/nom]Why anyone would use an iphone for GPS is beyond sane. GPS on an iphone is a gimmick and not a very good one. I had a friend who rode with me to Albuqueque NM, to pick up a vintage auto and he insisted on using his iphone for GPS. Well in NM, because of the mountains a phone signal is spotty and the iphone likes to use either cell towers or connection to download its info instead of storing anything and by the time we would get an update we had driven miles past our exits. I finally had to pull over and plug in a real GPS receiver into my laptop and we got to were we needed to be.[/citation]
I wouldn't use it as a hiking GPS, but I used a phone with a maps app for driving navigation for years.
