How to Install Apps on an iPhone 3G

By Jefe Nubarron

The iPhone is classified as a smart phone precisely because you can enhance the phone's base installation of features with additional applications or apps. Since the original iPhone was released, the number of iPhone apps has grown rapidly, and most of the apps available today can be installed on an iPhone 3G. There are two methods of installing apps on your iPhone, either through iTunes on you computer and subsequent syncing of them over to the device, or through the App Store via your phone.

Things You'll Need

  • iTunes Store account

Directly on the iPhone

Step 1

Locate the App Store icon on your iPhone. It is blue with a white "A" enclosed in a circle.

Step 2

Open the App Store app and navigate through one of the icons at the bottom of your screen. You can select apps according to the category they are in or their popularity, or you can even search for a particular name or description.

Step 3

Find an app that you would like to download to your phone. When you have found one, there will be a button in the upper-right corner of the screen that dictates the price or whether the app is free to download.

Step 4

Tap the price button and then tap it again once the text changes to "Buy Now." If you have not configured your iPhone with an iTunes account, you will be prompted to do so.

Step 5

Wait as the app downloads to your iPhone over the air. You will see a slightly dim icon and a small bar indicating the progress of the download. Once the download completes, you can tap and launch it.

Through iTunes

Step 1

Open the iTunes software on your computer and select the iTunes Store from the left column of the display.

Step 2

Sign in to the store, by selecting the "Store" menu at the top menu bar for iTunes and signing in from the menu item. If you see a "Sign Out" option, you are already signed in.

Step 3

Browse the app store in iTunes for an app that you wish to download, and click the "Buy App" button with your mouse.

Step 4

Connect your iPhone to your computer using the iPhone's USB cable.

Step 5

Select your iPhone in the left column, and then look for the Sync button in the main window. Synchronize your iPhone and all recently purchased apps will be installed automatically.
