group of smartphone models produced by Apple Inc.

One of the biggest complaints about the original iPhone was that it didn’t use 3G for wireless data, instead depending on the far slower – average data speeds between 75-135 Kbps – EDGE protocol . Another complaint was the lack of third-party apps. The iPhone 3G addressed both of these.

The iPhone 3G is very similar to the original iPhone except for the addition of 3G networking, with typical speeds in the 400-700 Kbps range, so about 5x as fast as EDGE, and a real GPS chip. The CPU is clocked to the same speed. It has the same 2 MP fixed focus camera. And it has a less powerful battery.

The other big improvement was iPhone OS 2.0, which for the first time supported third-party software on the iPhone using the App Store.
