The Fastest iPhone Ever
The first thing you´ll notice about iPhone 3GS is how quickly you can launch applications. Web pages render in a fraction of the time, and you can view email attachments faster. Improved performance and updated 3D graphics deliver an incredible gaming experience, too. In fact, everything you do on iPhone 3GS is up to 2x faster and more responsive than iPhone 3G.
Video
Now you can shoot video, edit it, and share it-all on your iPhone 3GS. Shoot high-quality VGA video in portrait or landscape. Trim your footage by adjusting start and end points. Then share your video in an email, post it to your MobileMe gallery, publish it on YouTube, or sync it back to your Mac or PC using iTunes.
Find My iPhone and Remote Wipe
If you misplace your iPhone, Apple´s MobileMe service can help you find it. Log on to me.com to view a map that shows the approximate location of your iPhone. If it´s nearby, have it play an alert sound to help you find it. If it´s not, you can display a custom message, remotely lock it with a passcode, or initiate a remote wipe and restore it to factory settings.
