The device was available in 8 and 16GB models, and features a 3.5-inch multi-touch screen display.
- The iPhone 3G is powered by an ARM11 CPU, running at 412 MHz. ARM11 processors are commonly used in smartphones, as well as home electronics like televisions, Blu-ray players and digital cameras. The iPhone 3G also uses a PowerVR MBX-Lite graphics processing unit. The GPU provides OpenGL abilities to the device, aiding in the production of 2D and 3D graphics.
- ARM was founded in 1990 and is headquartered in Cambridge, UK. According to ARM, the average smartphone on the market has at least three ARM microchips powering it. In addition to the sale of microchips, ARM focuses on designing and licensing intellectual property to other semiconductor manufacturers.
- In addition to processing power, the iPhone 3G's data speeds are tied to AT&T's 3G network. Mobile data rates over 3G average 600Kbps to 1.4Mbps, with peak rates up to 3.1Mbps. Data rates are independent of the iPhone 3G's processor and can fluctuate based on location.
