How to use FaceTime on the iPad

The front-facing camera on the iPad 2 and iPad 3 may not win an award for quality, but it does open up the iPad to the world of videoconferencing. For those wondering how to use FaceTime on the iPad, it's actually rather simple. The primary requirement to FaceTime with someone else who owns an iPhone, iPad or a Mac is to have their email address programmed into your iPad's contacts list. This tells FaceTime how to reach them and can be thought of as their FaceTime phone number. 

After launching the FaceTime app, you will be taken to a screen that shows the front-facing camera at work. On the right side of the screen is your contacts list, which you will use to pick out who to call. If the person you want to connect with is not on the list, you can add them by hitting the button with the plus (" ") sign in the upper-right corner. (One nice feature of iOS 5 is the sharing of information through the cloud, which can help keep your contacts from your iPhone to your iPad in sync.)
iPad Tips Every Owner Should Know

Because you don't place calls on the iPad, there's no need to fill in the person's phone number. Simply add their First and Last name and include the email address they have associated with their Apple ID.
To place a call, simply tap on the email address shown in the contact description. This will notify the person of the incoming request for FaceTime. Once they accept, the video conference will begin.
Note: FaceTime for the iPad uses the Internet to connect, so you will need to be connected to the Internet to place a FaceTime call.
