Best GPS App for iPhone 4

[billwill]

Is there a good GPS app for the iPhone 4? If so, is it available on the Apple App Store? TIA.

Yep. Tomtom, navigon, garmin etc are all available.

I personally use Skobbler, as I don't drive very often and most GPS apps are fairly pricy. Skobbler is cheap/free and good enough.

I have the TomTom app and love it. I added the traffic subscription (In app purchase) and it works quite well with updating my route to avoid issues.

How much data does that use up generally?

I'm grandfathered into the old unlimited data plan so I've never really payed attention. I think it says it updates the traffic every 15 min so I doubt it's pulling much. The map is stored locally so no data there.

I got the TomTom app as well and really like it. One big point for me was the app will work without cell or 3G/Net connection. As long as the GPS can pick up a signal it's all good.
