Hi, I have Tomtom installed into my 3G and despite the latest update of the fw to version 4,2, it still crawls to being almost unsable. as with many other apps. So, I am contemplating an upgrade of my 3G iPhone to an iPhone 4 (it is about time, one might add!) but before I do that I would like to know how it works with transferring Tomtom to my new iPhone. Any help would be appreciated. Thanks!
