In June 2008, Apple released iPhone 3G, the second generation iPhone, together with iPhone 2.0 software. It combined the original features of the iPhone with high-speed networking, a built-in global positioning system ("GPS"), a 2-megapixel camera, and a 3.5-inch touch widescreen.
The iPhone is available throughout the United States, Canada, Europe, and Asia.
"The iPhone uses a distinctive implementation of encryption which requires both a user's input (passcode or password) and a device-specific unique identification number (UID) to create the encryption key. The key is not stored on the device itself. Instead, when the user enters their passcode or password, the system combines that input with the UID and if the device decrypts, it was correct."
