QuickTime is a multimedia utility created by Apple, Inc., that is frequently used for sharing music and videos. If you own an iPhone, a QuickTime plug-in is included with your phone. This allows you to open QuickTime files received by MMS (Multimedia Messaging Service) and email. Your phone's QuickTime plug-in will also convert comparable media files to QuickTime so that you can play them back on your phone. If you are new to the iPhone, you can send yourself a test QuickTime file to practice using the multimedia utility on your phone.
Tap the "Email" or "SMS" icon on your phone. Locate a message with a QuickTime attachment. If none are available, you can send a test QuickTime file to your phone. Log in to your personal email account from your desktop computer and click "New Message" or "Compose." Type in the email address configured in your iPhone then attach a QuickTime file from your computer and click "Send."
Open your email account on your phone. When you have received the message, click the QuickTime file attachment at the bottom of the email. The file will appear as a QuickTime icon, but once downloading completes, it will become a long rectangular bar you can tap to launch your QuickTime application.
Tap the QuickTime bar once downloading completes. Your QuickTime application will launch in a new browser. The file will play automatically. You can replay it, but you cannot save it to your iPhone.
