Siri

The mystery as to why Siri is exclusive to the iPhone 4S just got a little more interesting. 9to5Mac ported the voice command system from the iPhone 4S to the iPhone 4. In the video below, developer Steven Troughton-Smith demonstrates how Siri looks on the device.

9to5 claims it can recognize spoken commands and speak back to the user. The only problem is Apple's servers are not authenticating commands from the iPhone 4 hardware. Apple fans have been debating whether other iOS devices like the iPad 2 can handle Siri's AI. 9to5's discovery proves there are no technical reasons for Siri being exclusive to the iPhone 4S.

New and existing Sprint customers can pre-order the iPhone 4 with iOS 5 for $99 starting on Thursday. The iPhone 4S can be pre-ordered at 12:01 AM PST (3:01 EST) on Friday via their online store. AT&T or Verizon customers can visit Apple’s website or call 1-800-MY-APPLE to order the iPhone 4S tomorrow.

The iPhone 4S features Apple's dual-core A5 processor, 8-megapixel camera, 1080p HD resolution video recording, iCloud and Apple's new voice command assistant Siri. The iPhone 4S is $199.99 for the 16GB model, $299.99 for the 32GB model and $399.99 for the 64GB model. All prices require a new or upgraded contract.

The iPhone 4S is not the "highly-anticipated" iPhone Apple fans were waiting for. It's safe to assume many fanboys were disappointed by Tim Cook's announcement, but Apple is sticking to its claim that this is the "most amazing iPhone yet." It didn't deliver a new "teardrop" design, or many of the other features we were promised, but it does have the rumored 8 megapixel camera and A5 chip. Hate it, love it or just don't care, here's a list of all the specifications and features for the new iPhone 4S.

It looks a lot like the iPhone 4, but Tim Cook promised the latest Apple iPhone is "all new inside." The Apple CEO unveiled the iPhone 4S (not the iPhone 5) in Cupertino on Tuesday. The new iPhone features a dual-core A5 processor, 8-megapixel camera, and GSM and CDMA radios.

The iPhone 4S offers 8-hours of talk time (3G), and six hours of web browsing time (3G). It also features image stabilization, facial recognition, 1080p video recording capabilities and the new Siri voice control feature.

The iPhone 4S will be available in the US from AT&T, Verizon and Sprint on October 14th. Pre-orders begin this Friday, October 7th. The 16GB model will cost you $199, the 32GB version is $299 and 64GB version will retail for $399.
