When shopping on your iTunes 4S in the iTunes Store for movies, you can either rent or buy content. If you rent, which is less expensive, you have 30 days from the time you rent the item to begin to watch it. After you have begun to watch it, you have 24 hours from that time left to watch it as many times as you like.

  1. With iTunes open, tap the Videos button.

  2. Locate the movie you want to rent and tap the arrow to the right of the movie.

  3. In the detailed description of the movie that appears, tap the Rent button.

  4. The gray Rent button changes to a green Rent Movie button; tap it to confirm the rental. The movie begins to download to your iPhone immediately, and your account is charged the rental fee.

  5. To check the status of your download, tap the Downloads button. The progress of your download is displayed. After the download is complete, you can use the Videos app to watch it.

Some movies are offered in high-definition versions. These HD movies look great on that crisp, colorful iPhone screen.

You can also download content to your computer and sync it to your iPhone.
