How to use FaceTime on iPad 2, iPhone 4, iPod touch or Mac
FaceTime is Apple’s video chat feature that allows users to connect over Wi-Fi using an iPad 2, iPhone 4 or later, iPod touch (4th gen.) or a Mac.
How to use FaceTime on iPad 2 and iPod touch
If you are using FaceTime from an iPad 2 or iPod touch you can tap on the FaceTime app icon to get started. If you are not signed in you will need to do so or if you haven’t set up an Apple ID you can create a new account using the FaceTime app.
After you are signed in you can call someone by taping on Contacts on the bottom right corner in the FaceTime application, then select someone you wish to call and tap the camera icon next to their email address or phone number. The person you are calling must have one of the Apple products listed above that’s compatible with FaceTime and they must be signed in with their Apple ID.
An alternative way to make a FaceTime call is to tap on the Contacts app, find the person you wish to call and tap FaceTime.
FaceTime is also listed in Setting app. The Setting app will allow you to turn FaceTime off / on, sign in and add additional email addresses where you can be reached.
Using FaceTime on iPhone 4 and 4S
FaceTime uses the phone number and the email address for iPhone users. When you log into FaceTime with your Apple ID, your phone number is automatically registered for FaceTime use.
Unlike the iPad 2 and iPod touch there is not a separate application for FaceTime. Instead FaceTime is part of the phone application. You can tap the FaceTime icon to invite the other party to a FaceTime call during a phone call or you can find the person in your contacts app and tap FaceTime.
Using FaceTime on a Mac
FaceTime for Mac is free for users that have OS X Lion. The application on a Mac is almost identical to the iPad 2 app and is just as simple to use. There is also an HD FaceTime app that use can download at the Mac App Store for $0.99.
