History of Apple Inc.
The first version of the iPhone became publicly available on June 29, 2007 in selected countries/markets. It was another 12 months before the iPhone 3G became available on July 11, 2008. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. This 12-month iteration cycle has continued with the iPhone 4 model arriving in similar fashion in 2010, a Verizon model was released in February 2011, and a Sprint model in October 2011, shortly after Jobs' death.
Jochen Claussen-Finks
Sliding Calendar invention in 1984. The conceptual idea of the calendar was to create something thin and intelligent smooth to use with one hand. The desired month is adjusted in a small window on the front from a code system on the back. The first company to use the calendar as a giveaway was IBM to promote the introduction of the Personal Computer with Charlie Chaplin as a cover print in Germany. The calendar works without a battery. After the white version, Claussen-Finks developed a relief surface for a black version of the calendar giving the impression of an electronic device. The permanent sliding calendar was invented by Claussen-Finks 24 years before Apple presented its first iPhone in 2008, where sliding on the screen with the finger appeared in an electronic consumer product for the first time.
