What is the model number of the original iPhone?

The model number of the original iPhone was A1203. This identifies the first-generation iPhone hardware, often informally called the iPhone 2G because it used GSM and EDGE cellular technology rather than 3G networks.

Apple unveiled the device on January 9, 2007, combining a mobile phone, widescreen iPod, and internet communicator in one product. It went on sale in the United States on June 29, 2007, initially with 4 GB or 8 GB of storage. The phone introduced Apple’s multi-touch interface, Safari web browsing, visual voicemail, and a software keyboard without a physical keypad.

A1203 is a hardware model identifier, not the product’s retail name or a carrier-specific marketing label. Later iPhones received different model numbers, such as the iPhone 3G’s A1241, which is why the number helps distinguish the original generation.

The device lacked several features now considered standard, including 3G connectivity, GPS, copy and paste, and third-party App Store applications at launch. Apple’s App Store arrived in 2008 with iPhone OS 2.0.
