iPhone 3G

Next up in the iPhone release order is the iPhone 3G. Whilst much of the exterior design didn’t change, the iPhone model’s most notable advancement was its ability to access 3G mobile data. The iPhone 3G ran much the same software as its predecessor. It’s safe to say this was the iPhone that catapulted the phone into the market as the must-have mobile device.

The iPhone 3G was 12.3mm thick and had a 3.5″ display screen and a 2MP camera, along with a 128MB memory. Everyone seemed to love it as much as the anticipation built up – it sold a million units for $699 in the first weekend of its release, paving the way for the next iPhones that would only follow in its footsteps. A 3GS model would follow, with the ‘S’ standing for speed and including performance improvements, a three-megapixel camera with higher resolution and video ability, and voice control.
