The iPhone 3GS is Apple's 2009 upgraded model of their most popular device. The iPhone 3GS is all about speed (hence the "S" in the name). Faster processor, faster video, faster data via HSDPA 7.2 (if your non-AT&T network supports it), and video capture backed by more storage. 3GS gets an upgraded camera with auto-touch-focus and VGA video capture, but the big news is software-related: Voice control, support for software-enhanced dock accessories, remote wipe and "Find my iPhone" features via MobileMe, and more.
What can I say it's as Good As it Gets. I really didn't know that they made a 16GS so Soon. BUT I'm not sure if I wanna UPGRADE since I have a 16GB 3G. BUT..I like it and I'll always be a Iphone Fan.
