iPhone 3GS

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.

3-Megapixel Camera
The new 3-megapixel camera takes great still photos, too, thanks to built-in autofocus and a handy new feature that lets you tap the display to focus on anything (or anyone) you want.




Voice Control
Voice Control recognizes the names in your Contacts and knows the music on your iPod. So if you want to place a call or play a song, all you have to do is ask.


Compass
With a built-in digital compass, iPhone 3GS can point the way. Use the new Compass app, or watch as it automatically reorients maps to match the direction you’re facing.


Cut, Copy & Paste
Cut, copy, and paste words and photos, even between applications. Copy and paste images and content from the web, too.
