who makes the best GPS App for the IPhone? I need one that will show satellite images and topos. I want something that will work well for hunting in the mountains.
I have not searched for a GPS app for the Iphone however depending on where you are in the mountains a signal may not be available. If it were me I would purchase a Garmin gps they make several quality models for most any budget. Iphones are great(own one)but trusting one to get me back to camp I would be very hesitant to rely on it. Just my thoughts.
I used an app called my topo when I went to CO a few years ago. It was good for a map study but was not a good nav tool. Not sure how it is today but back then you had to download all the maps on wifi, so not on the mountain. I used a GPS and a compass for nav.
I downloaded a free app called Trimble Outdoors Navigator. It gives both sat images as well as map. You can record your tracks as well as use it to navigate back to a point.

Why would a garmin get better satellite signal in the mountains than an Iphone?
Iphone or gamin, they all have an accuracy of about 3 meters... good thing about an Iphone is it can at least give an approximate location using cell towers.
iPhone uses Wireless 3G/CDMA towers not satellite for GPS. It measure the distance to the towers.
No... Iphones (at least the the Iphone4) has a gps antenna and it will work fine with or without cell phone coverage. It only uses distance between towers when there is no GPS signal available.
All of the GPSs iphones and garmins have the same accuracy and none are able to pick up a better signal than any others (some might pick up on GLONASS which would help you in finding signal)... They are just recievers, their really is not much to them. Heck, an Iphone might even work better, I bet there is an app somewhere that could process your gps data and get your location down to the tenth of a foot... but who really needs that?
I have an Iphone 4. If I dont have service, none of my GPS apps work.
Then you have a setting messed up somewhere, or havent given ur phone enough time to "find" you.
If you dont have any cell service, it could take up to 5 minutes to determine your location and that goes for iphones, garmins, or magellans... with A-GPS which is what your phone uses when it has cell signal, it should take less than a minute.
The only bad thing about these apps for the phones is they will suck the juice out of the phone. On mine, at least by 50%. I haven't uploaded an app yet that will extend your battery tho.

The GPS will get you within 3 meters.
I agree, GPS will work on an iphone without cell service. The problem with most iphone apps is that they uses the cell service to download maps, most are not stored locally.
Therefore, you may get an accurate GPS signal, but you may not be able to layer your position on top of a map, making the position un-useful in most cases.
