In the music industry, they talk about the “difficult second album.” Fortunately that didn’t hold true when it came to Apple releasing its highly successful second-gen iPhone, which it unveiled for the first time on June 9, 2008.
Adding GPS, 3G data and a higher-quality build than its predecessor, the iPhone 3G was arguably just as revolutionary for what it did on the software side. iOS 2 arrived at the same time, and introduced push email, turn-by-turn navigation and, most significantly of all, an App Store — something Steve Jobs had previously been adamant Apple would’t allow.
Check out the debut of the iPhone 3G below.
