iPhone 3GS - 8GB Black

Keep applications open in the background. Organize your apps with folders. Shop for books is in the iBookstore. Now you can run your favorite third-party apps - and switch between them instantly - without slowing down the performance of the foreground app or draining the battery unnecessarily. So you can listen to a ball game while emailing. Drag and drop to organize apps into folders on your Home screens and get fast access to your favorites. More than a full-color ebook reader, iBooks is also an amazing place to browse and shop for books anytime you feel like it. It works with PDFs that you can sync using iTunes on your Mac or PC. And you can customize iBooks to suit the way you read - adjust the brightness, change the text size, and more. On iPhone, making a call is as simple as tapping a name or number. And Visual Voicemail lets you play messages in any order - just like email.
