Disconnecting iPhone from Your Computer

You can disconnect iPhone from your computer at any time. However, if you disconnect it while a sync is in progress, some data may not get synced until the next time you connect iPhone to your computer.

When iPhone is syncing with your computer, iPhone shows “Sync in Progress.” If you disconnect iPhone before it finishes syncing, some data may not get transferred. When the sync is complete, iTunes shows “iPhone sync is complete.”

Cancel a sync: Drag the slider on iPhone.

If you get a call during a sync, the sync is canceled and you can disconnect iPhone to answer the call. Connect iPhone after the call to finish syncing.

Connecting to the Internet

iPhone connects to the Internet whenever you use Mail, Safari, YouTube, Stocks, Maps, Weather, the App Store, or the iTunes Store.

How iPhone Connects to the Internet

iPhone connects to the Internet using either a Wi-Fi network or a cellular data network. iPhone does the following, in order, until connected:

ÂÂ Connects over the last Wi-Fi network you used that’s available.

ÂÂ If no previously used Wi-Fi networks are available, iPhone shows a list of Wi-Fi networks in range. Tap a network and, if necessary, enter the password to join. Networks that require a password show the lock icon next to them. You can prevent iPhone from automatically showing available networks. See “Wi-Fi” on page 189.

ÂÂ If no Wi-Fi networks are available or you choose not to join any, iPhone connects to the Internet over a cellular data network (, , or ). You can prevent iPhone from using cellular data in Settings. See “Network” on page 193.

If a Wi-Fi network or a cellular data network isn’t available, iPhone can’t connect to the Internet.

Note: The 3G (UMTS) cellular network supports simultaneous voice and data communications on GSM models. For all other network connections (EDGE or GPRS on GSM models, or EV-DO or 1xRTT on a CDMA model), you can’t use Internet services while you’re on the phone unless iPhone also has a Wi-Fi connection to the Internet.

Many Wi-Fi networks can be used free of charge including, in some countries or regions, Wi-Fi hotspots provided by your iPhone carrier. Some Wi-Fi networks require a fee. To join a Wi-Fi network at a hotspot where charges apply, you can usually open Safari to see a webpage that allows you to sign up for service.
