I think it depends on how 'tech savy' you are as to which option will work best for you. If your worried about not getting reception from cell towers I'd get a separate gps so you don't have to worry. i've had google maps fail when I was about 4 hrs away and didn't have a clue where I was going. It's also taken me to the the wrong location a couple times. That being said most of the newer phones have some sort of gps built in that you can use and for the most part they work fairly well. In terms of the cell phone, If your looking for something thats easy to learn/use I'd go with the iPhone. Most people can pick it up, learn to use it fairly quickly, and it will do everything you want it to and more. The other big one these days is the android phones samsung, htc, lg, etc. I have one of these and for me its great, but it's a little bit harder to navigate around and change things if your not used to it. So your best bet is to go to a cell phone store and try out the phones on display to figure out which one is best for you. Keep in mind that some of the sales reps work on commission so get what you think is going to work the best for you. Hope this helps.
