The 3G S version comes equipped with a 3-megapixel camera with video capturing and editing capabilities, improved battery life with up to 12 hours of talk time and 30 hours of audio, voice-command control, and a built-in digital compass.

"The new iPhone is redefining what people can do on a phone," said Chad Evans, an app designer for mlb.com. "We're now able to live stream complete games on a handheld device."

The 16-gigabyte iPhone 3G S can be had for $199 with a new contract with exclusive carrier AT&T. The 32-gigabyte version costs $299 with a new activation.

Apple will also continue to sell a second-generation iPhone 3G with 8 gigabytes of memory for $99.

The new OS 3.0 operating system, which was launched last week, comes installed on the iPhone 3G S, and is available for free download on all existing iPhones. OS 3.0 enables users to cut, copy and paste for all applications, which iPhone users have long demanded. The operating system also features an undo gesture, which will undo the last action by shaking the phone.
