Edit your own satnav maps with TomTom for iPhone

This brand new update to the ever popular TomTom for the iPhone app (which has featured in the Apple 'top grossing apps' list since it was first released 18 months ago) adds one highly requested feature: Map Share. Why the big hurrah over one additional feature? Simple, it's a hugely important part of the TomTom feature set and long overdue in iPhone form. What Map Share does, and does brilliantly it has to be said, is allow users of the iPhone app to make changes to their own maps as well as benefit from the changes and updates made by the community of TomTom users. Possible changes include editing of street names, setting driving directions, speed restrictions and so on.
