iphone gps capability–if you have an iphone, you will wan to know how can I turn on the GPS in iPhone? or do I need other iphone gps receivers?
in fact iPhone does not come with any GPS capability. No such functionality exists and this is a big fault for iphone. but if you want to have map functions as gps, you can adopt google mobile maps. it just as good as gps for you.
Google Maps should come close and use the triangulation of cell towers to give you an approximation …
