I have an old iphone that I need to transfer all my contact to my new iphone. How do I do this?
If you have iCloud on your old phone, sync your contacts to iCloud (Settings>iCloud>Contacts>On). Then set up your new phone with the same iCloud account and turn on Contacts syncing with iCloud. If prompted, choose merge.
