iPhones System Requirements

iPhones are unlike most other cell phones. Like the iPod, you’ll need a computer to connect your phone to. iPhones need to connect to computers regularly to synchronize music, videos, photos, e-mail, contacts, calendars, and more. You also won’t be able to activate your phone on the AT&T network until you successfully connect your iPhone to Apple’s iTunes program. For the iPhones in production at the time of publication, the computer system requirements are as follows:

» A Mac computer running OS X 10.5.8 or newer with a USB 2.0 port, or a Windows computer with a USB 2.0 port and Windows 7, Vista, or XP Home or Professional with Service Pack 3 or newer. Note that the system requirements are constantly changing as both iPhone and computer features evolve. We recommend viewing the most recent system requirements before you make any purchase decision (http://www.apple.com/iphone/specs.html).

» iTunes 9.2 or newer.

» iTunes Store account.

» Internet access.

Before you purchase an iPhone, make sure that you have a computer on hand that is up to the task.

 NOTE: If you haven’t installed iTunes on your computer, download a free copy from http://www.apple.com/itunes. Versions are available for both Mac OS X and Windows systems, and they’re easy and quick to install.
