IPhone (1st generation)

The iPhone 2G (also known as iPhone EDGE or original iPhone) was the first generation iPhone designed by Apple Inc. It was announced on January 9, 2007 in Europe at the Macworld Conference & Expo 2007 and on June 29, 2007 it was introduced in the United States. It featured a quad-band GSM with GPRS and EDGE.

The original iPhone no longer receives software updates from Apple, it's final software version was iPhone OS 3.1.3 due to incapable hardware.

Design
The original iPhone had a glass multi-touch touchscreen display and introduced 5 physical buttons that remained the same over the newer generations of iPhone. The back of which was made of brushed aluminum with a black plastic base, required because metal shields cellular and Wi-Fi signals. The camera was located in the upper-left corner of the iPhone's rear. The headphone socket was recessed into the casing, making it incompatible with most headsets without the use of an adapter. Other models do not have this issue.

Hardware
Apart from the unknown-purpose Apple 338S0297 in the iPhone, Apple had no hardware of theirs for the iPhone and, instead of starting on their own hardware to only use in the iPhone (the consumers who couldn't wait for the iPhone told Apple Inc. it would take years), they used the following hardware from other companies:
 * Samsung S5L8900 Application Processor
 * ARM 1176 32-Bit Core Processor
 * ARMv6 Instruction Set
 * 667Mhz (underclocked to 412Mhz to prevent overheating)
 * 128MB SDRAM
 * Integrated PowerVR MBX Lite Graphics Card
 * Samsung K9MCG08 (NAND Flash Storage)
 * Marvell W8686 (Wi-Fi)
 * CSR BlueCore4 (Bluetooth)
