Definition[]
In June 2007, Apple, Inc. introduced the iPhone, which combined in a single handheld product a mobile phone, a widescreen iPod with touch controls, and an Internet communication platform. It was one of the world's first "smartphones" and remains one of the most popular consumer electronic devices in the world.
Overview[]
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.
In June 2009, Apple launched the iPhone3G[S], which offers improved performance (including longer battery life and faster web browsing), a 3-megapixel, autofocus camera, and hands-free voice control.
iPhone users have access to Apple's iTunes App Store, which offers software applications for the iPhone. Over 100,000 applications are available to iPhone users.
The iPhone is available throughout the United States, Canada, Europe, and Asia.
Encryption[]
"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."[1]
