Steve Jobs KOs iPhone OS 4.0 upgrade for original iPhone

iOS was once upon a time called iPhone OS, or "operating system", which is the software that provides all the basic device functionality and is the interface between the hardware and applications. iOS was introduced with the iPhone on January 9 2007, and it was originally not intended to be programmable by third parties. Steve Jobs had envisioned that developers could create Web Apps that would run in the browser. This changed less than one year after when the iPhone SDK (software development kit) was introduced in October 2007. Today, hundreds of thousands of apps have been created for this platform. iPhone OS became iOS on June 2010. Interestingly, both iPhone and iOS were former trademarks of Cisco, that Apple now uses under a license. 

Steve Jobs Steve Jobs (1955-2011) was the co-founder of Apple Inc, which he created with Steve Wozniak on April 1 1976. The pair introduced personal computing with the Apple IIe. Steve jobs has also created Pixar, which he sold to Disney in 2006 and Next, a computer company that eventually merged back with Apple. Today's OS X is largely based on the work done at Next. After leaving Apple in 1985, Steve Jobs came back in 1996 in an advisory role and became permanent CEO again in 2000. Under his watch, Apple will execute projects like the iMac, iPod, iPhone and iPad.
