iphone 3G has a built in GPS, meaning it tracks you where ever you go. I dont have internet package with the phone. But if I turn on the GPS is shows a Blue Dot moving on white blank screen or cached maps for couple of miles in memory. After that its become white backround screen with blue dot moving.
I want to know is there any application which has like preloaded GPS maps, like a normal GPS so that we dont depend on internet connection to provide backround maps. Is it possible ? Does any one know of any such application or package that we can install ?
I also want to know how this offline google maps are done. There seem to be no guide on how to do this. Really appreciate it if anyone gives a guide on how this can be done.
