Connect to the Internet
iPhone connects to the Internet whenever necessary, using a Wi-Fi connection (if available) or
your carrier’s cellular network. For information about connecting to a Wi-Fi network, see Connect
to Wi-Fi, above.
When an app needs to use the Internet, iPhone does the following, in order:

Connects over the most recently used available Wi-Fi network

Shows a list of Wi-Fi networks in range, and connects using the one you choose

Connects over the cellular data network, if available
Note: If a Wi-Fi connection to the Internet isn’t available, apps and services may transfer data
over your carrier’s cellular network, which may result in additional fees. Contact your carrier
for information about your cellular data plan rates. To manage cellular data usage, see Cellular
settings on page 179.
Apple ID
Your Apple ID is the account you use for just about everything you do with Apple, including
storing your content in iCloud, downloading apps from the App Store, and buying music, movies,
and TV shows from the iTunes Store.

signing into iCloud with your Apple ID, then making sure that the features you want to use are
turned on.
Set up iCloud. Go to Settings > iCloud. Create an Apple ID if needed, or use your existing one.
iCloud stores your photos and videos, documents, music, calendars, contacts, and more. Content
stored in iCloud is pushed wirelessly to your other iOS devices and computers signed into iCloud
with the same Apple ID.
iCloud is available on devices with iOS 5 or later, on Mac computers with OS X Lion v10.7.5 or
later, and on PCs with iCloud for Windows 4.0 (Windows 7 or Windows 8 is required).
