Operating System and Performance
The iPhone launched with iOS, a groundbreaking operating system that offered an intuitive touch interface. While the original model was upgradable to iOS 3.1.3, its core functionality was revolutionary, introducing features like visual voicemail and a multi-touch interface. Powered by a 412 MHz ARM 11 processor and equipped with a PowerVR MBX GPU, the iPhone delivered sufficient performance for its time, although it was not aimed at intensive multitasking or demanding applications. The lack of a card slot limited memory to internal options of 4, 8, or 16 GB.
