50 years ago, the telephone was a very luxury item for us. In 1973, Dr. Martin Cooper released the first cell phone, marking a milestone for humanity. Since then, the mobile phone is constantly evolving and integrating many functions, bringing people many benefits. In the early stages, however, the phone is just a means of making calls and a few other simple utilities. It wasn't until the iPhone came out with the miraculous creation of Steve Jobs that people have the full concept of a smart mobile phone and enjoy its amazing features.

The birth of the iPhone indeed made people think a lot. For Apple's achievements in general and the iPhone in particular, we can't help but mention its founder: Steve Jobs. Steve Jobs is an American businessman. He is also the co-founder, former chairman of Apple. Technology genius Steve has seen the trend of smart phone development. For a long time, he has thought of a perfect product with absolute security system and outstanding features, providing peace of mind for users in the information age today.

Without hesitation, Steve Jobs brought the idea to the board of shareholders in an important press conference. However, the company's business is stagnant due to fierce competition from other phone companies, Steve Jobs' proposal of new ideas was not the right time.

With great faith in his thinking, Steve Jobs persisted with it. On January 9, 2007, Steve Jobs introduced to the public the first iPhone. But it was not June 29, 2007 that the new iPhone was released in the United States after a period of rumors and speculation. This is also the only iPhone with the longest time from introduction to release in Apple's history.

The iPhone has a very noisy development. Steve Jobs has been trying very hard to bring the iPhone to the world with all the power he has. Perhaps, he wants to fix the mistakes of Apple already before and bring new vision and new heights to this famous software company.
The two slogans used by the company at the time were "Apple reinvents the phone" and "This is only the beginning" (This is just the beginning). However, this version still has many flaws and poor functionality, so it is not trusted by consumers as expected.

In July 2008, Apple officially announced the second generation iPhone called iPhone 3G. In this version, though, the features have not been completely improved. But thanks to good advertising and marketing, the iPhone 3G has been sold in a large number. With this generation, Apple has adopted its slogan "The first phone to beat the iPhone" or "The iPhone you have been waiting for". )
