It's been almost 20 years since Steve Jobs changed the world forever, unveiling the first ever iPhone on stage at Macworld in San Francisco on January 9, 2007. The Apple co-founder introduced the device as a combination of an iPod, a phone and an internet communicator, famously declaring that 'today, Apple is going to reinvent the phone.' The iPhone went on sale later that year on June 29, priced at $499 for the 4GB model and $599 for the 8GB model, both requiring a two-year contract with Cingular. Crowds gathered around display cases just to catch a glimpse of the device, snapping photos through the glass as tech fans and journalists scrambled to see it in person. It went on to become one of the best-selling products in history, with more than 2.3 billion iPhones sold worldwide to date. #apple #stevejobs #iphone #viral #tech
