The first concept for an iPhone type device came about in 2000 when Apple worker John Casey sent some concept art around via internal email, he called it the Telipod - a telephone and iPod combination. It was Apple co-founder, Steve Jobs who directed Apple's engineers to develop a touch screen, mobile phone. Jobs at first was considering an Apple tablet computer, that desire eventually manifested in the iPad, and Apple had already produced a palm device with a touch screen, the Newton MessagePad.
