Buckled early and sprung for TomTom's iPhone GPS app, did you? If so, that very app just got a lot better today, as version 1.6 has brought TomTom's Map Share -- a crowdsourcing aspect that'll keep your maps more up-to-date than you ever thought possible. Map Share enables iPhone users to make changes instantly to their own maps and to benefit from free map updates made by the TomTom community and verified by the company itself. That means that users will now be able to edit street names, set driving directions and block / unblock streets directly on their maps, and if you're kind enough, you can share those updates
