TomTom has updated their mobile app for the Apple iPhone.

The app has been updated with improved user interface that is optimized for the retina display on the iPhone 4.

It also now has a new feature named navigate to photo.

Essentially, you point it to a geotagged photo stored on your phone and it would retrieve the data from it and take you there!

Pretty useful update for existing customers. New customers would have to pay USD 50.
