Oft- tough one. Actually, if you track the evolution of mobile phones for all different companies, lot of teams arrived at ‘smart phones’ at around the same time. iPhones are my favourite though! They came out in June 2007. Apple have lots of different inventions trapped inside the iphone, and lots of different legal things called patents (over 200) which explain the sensors and recievers and touch screen and apps, and the different inventors who made them. John Casey, a creator at apple, planned a telephone-iPod combination in 2000. Steve Jobs, the legend of Apple, told everyone to start working on a touch screen. We largely credit the creation to him!
