After visiting the updated telusmobility site, I noticed that the 4000 "may" have some new changes. Under "phone features", it is stated that it comes with voice activated dialing, speakerphone, voice memo, new ringers, calender, etc. Can this be confirmed or are these features for the 4500. They sure do sound exactly like the same features as the 4500. I would figure this to be an error.
