The Apple Store now offers the Unlocked Apple iPhone 4S 16GB Worldphone in Black (pictured) or White for $649 with free shipping. (Click “Select an iPhone”, choose a color and a model, then select “Or get iPhone unlocked and contract-free” at the bottom of the page.) It’s the first time we’ve seen the unlocked version of Apple’s latest iPhone for sale. Sales tax is added where applicable. The iPhone 4S is powered by the Apple A5 dual-core processor and features a new 8-megapixel camera which is capable of recording 1080p video at 30 fps with image stabilization. A dual-antenna system has also been added, which purportedly provides faster downloads and improved call quality on both CDMA and GSM networks. It also features AirPlay Mirroring, Siri voice-activated assistant, an 8-hour battery life, and more.

Of note, the unlocked versions of the Apple iPhone 4S 32GB and the Apple iPhone 4S 64GB are available in Black or White for $749 and $849, respectively. All models qualify for free shipping and are scheduled to ship in one to two weeks.
