The Apple iPhone can easily be turned into a keyboard for your Macintosh computer or PC by downloading a third-party application. This application can be downloaded from the App Store application on your iPhone and requires an iTunes account to purchase it. Once downloaded, this application converts your iPhone into a keyboard, which connects to your computer by using your computer's shared Wi-Fi connection. While the phone is being used as a keyboard you can plug it into your computer, which charges the phone while you're using it.
Press the "Home" button on your iPhone, and tap the "App Store" icon on the screen.
