I am so glad to have iPhone with me everyday and night. Especially this 2 days when I have to report work at Jurong whereby is hard to find your way at factory area. My iPhone GPS doing well in order to guide me.
But others don't see the same like me. They find that by launching iTune to Sync with iPhone is a kind of waste time. I will say if music, video and photo are all control by the same application and sync in one shot. It will reduce a lot of time and effort.
Blue Tooth not able to transfer files is a way to restrict iPhone to leak out corporate information. As well as not able to send contact information.
