The SDK states that you cannot make turn by turn direction based software for the iPhone. Correct me if I am wrong (no I didnt search threads, I only have a few mins to type this) but.. they mean you cant use the built in Google maps for this. Basically, TomTom could make a turn by turn app for the phone, but they have to use their own maps. Am I wrong here? I believe without a doubt, TomTom and Garmin will be allowed to make GPS turn by turn software for the iPhone, they just cant use the Google maps program for this purpose - thus, the restriction.
