Transfer iPhone contents to iTunes How do I transfer the contents of my iPhone to iTunes before I get a new iPhone? I want to be able to then load all my contacts, text messages, photos, etc. to my new iPhone.
You can use iTunes that will transfer your old phone data to your Mac (and back to new phone)

or

You can use iCloud that will back up your old phone to iCloud (and back to new phone)

Do not forget the actual Phone function (the SIM card), use the old or use the new (if you got one).

Very specific instructions for all methods above are available from Apple here..

I personally prefer the iTunes to my Mac method.
