On July 11, 2008, the iPhone 3G was launched, featuring GPS, faster 3G data, and a new mobile operating system, iPhone OS 2, with the introduction of the App Store.
The iPhone 3G marked a shift in design with a curved plastic backing and introduced 3G cellular networking, improved data speeds, clearer call reception, and GPS.
The launch of the iPhone 3G also brought a lower price point of $199, making it 60% cheaper than the original iPhone, and the App Store in iPhone OS 2 revolutionized iOS devices.
The iPhone 3G was a significant success for Apple, selling 1 million devices in its first weekend and contributing to the device's global popularity.
