The TomTom iPhone Navigation App just got updated which should interest the original iPhone or iPod touch users. Version 1.2 adds support for the iPod Touch and first-generation iPhone and also features updates to maps and IQ Routes.
The update also enhances the overall functionality, fixes bugs and adds Advanced Lane Guidance in both portrait and landscape mode. To run this application on the iPod touch and and 1st-gen iPhones, TomTom's car kit is required as these devices lack an integrated GPS receiver. iPhone readers would be interested to know that we here at iSmashPhone reviewed five other GPS apps which you can read about here.
