So another 1.8GB download for me... About a week ago TomTom updated to 1.4 for iOS4 compatibility and added a number of features. Today there' another one. This is very unusual as it's normally months between updates from TomTom. The app store doesn't really give any clues as to what they've done in this release, they just repeat the list of changes from 1.3 to 1.4. I'd be very interested to know what/why etc... Anyone got any clues?
