IPhone (1st generation)
The original operating system for the original iPhone was iPhone OS 1, marketed as OS X, and included Visual Voicemail, multi-touch gestures, HTML email, Safari web browser, threaded text messaging, and YouTube. However, many features like MMS, apps, and copy and paste were not supported at release, leading hackers jailbreaking their phones to add these features. Official software updates slowly added these features.
