My understanding is that they will be disabling it on my iPhone 4 & putting a better version of Siri on the iPhone 4 S Also, I will be getting a better camera & it will be faster. Come on guys! What more could you want. These are Apple products. Think about the status you get. It's worth the upgrade for me. Only $300.
