iPhone 4 vs 4S

Recommended Posts

Looks like I will be getting an iPhone 4 soon. But I was wondering is the 4S better for location? I saw one of the feature comparison lists show that the 4 has "assisted GPS" and the 4S and 5 have GPS (and maybe GLONASS). Anybody out there have experience with the 4? I normally use a hand-held GPSr, this would mostly be for when we are just out and about. Your thoughts, experiences?

Don't quote me on it but I believe that assisted gps operates of the positions of wifi/cell networks and GPS operates of the satellites so the 4s would be more accurate. (My 4s can get 5-10m accuracy). I'm not sure the exacts of the 4's accuracy though.

Thanks. That is what I was figuring as well. I spoke with a few iPhone 4 owners locally and it sounds like the accuracy is similar to the 4S but maybe not in all situations.

I have the 4 and I find it's plenty enough accurate for Geocaching. I think the "assisted GPS " just means that it uses cell tower triangulation AND on board GPS ....the cell towers to get a quick though less accuarate fix while the satellites are connecting, and the GPS for accuracy once the satellite connection is made.
