IPhone 3G

iPhone 3G is the 2nd generation of iPhone, which was released in 2008. The iPhone was known for having a 3G modem and being super cheap, starting at $199. This was nicknamed by Apple as the first phone to beat iPhone according to Apple. This product is also known for its second generation iPhoneOS (iOS' former name).

This was very minor upgrade from the iPhone 2G, but the product sold very well.
