I think our wrong concept of using GPS in iphone needs 3G/EDGE's data connection is rooted in our mind.. To make things clear, a general GPS device does not need all this.. Why iphone need this if u are using their native google maps.. BECAUSE, the google map is not store on the iphone.. Therefore, each time u use the NATIVE iphone google map for GPS navigation.. 3G/EDGE is needed to LOAD the map..
Tomtom, Sygic STORED maps INTO iphone... Same like Garmin & others GPS device.. So, NO 3G/EDGE data services is needed.. hope this is clear to all..

boss..
firstly, u must understand tat u r being charged for using maps as a gateway 2 use da gps service...maps app doesnt hv preloaded map data hence requiring da phone 2 use data services 2 get da map...
da other apps, they hv preloaded specific countries map data with da app...so, thr is minimal data used
da gps, is always free.. its a chip in da phone which connects to certain satellites to determine ur location...
its da app which u hv which determines whether u r being charged or not..

in short, using Maps to
triangulate your current position won't get you charged for any data usage. however, the
routing function will require your phone to download the maps thus connecting to 3G/EDGE/GPRS services.
so if you don't wanna get charged for that, get GPS navigation apps from
Sygic or
TomTom (not out yet). or like what some have mentioned,
Offline Maps from Cydia or
OFFmaps from App Store.
P/S: for GPS usage/discussions, the proper thread is
share your iphone 3G GPS usageThis post has been edited by teikwing: Jul 29 2009, 11:01 PM
