I've decided to get rid of my iPhone 4 [proximity sensor is killing me] and was wondering how the transition would be? I've had the iPhone ever since they originally came out so I've gotten pretty used to the way contacts sync and everything. Can someone give me any helpful advice as to how things are going to sync with a Macbook Pro and what not? Are there any programs in terms of iTunes that I will need/want to manage everything? Thank you for your time.
