How do I sync all my Apple devices?
Automatically sync all content: This is the quickest and easiest option. Simply select the “Automatically sync when this [device] is connected” checkbox in the General pane, then turn on syncing for each type of content you want to sync. Your Mac and iPhone or iPad update to matching content whenever you connect them.
Can I attach my iPhone to my iPad?
You can connect an iPhone and iPad through iTunes or iCloud to sync the devices, making desired content and apps available on both. You can also connect the two devices through a personal hot spot to share an Internet connection, if the feature is available in your area.
