Logitec LDT-1Si41 turns your iPhone 4 into a portable TV

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. 

iPhone: iPhone: The iPhone is Apple's line of smartphones. That was also the original name of the first iPhone, which was announced on January 9th 2007 by Steve Jobs during the Macworld Keynote. The iPhone was released to the public in June of the same year. The development of the iPhone started in 2004, was internally called "project purple" and was the fruit of a collaboration between Apple and AT&T. Since then, Apple has released new iPhone models every year, with the iPhone 3G in July 2008, the iPhone 3GS in June 2009, the iPhone 4 in June 2010, the iPhone 4S in October 2011 and the iPhone 5 in September 2012. The iPhone represented more than half of Apple's revenues in 2012.
