Apple has gone a long way from January 9, 2007 when the first iPhone was officially announced. During the years, the Cupertino-based company introduced updated versions of its smartphone and at the time I’m writing this, the iPhone 4 is still selling pretty darn well. Not in huge volumes, but the reason is that the next iPhone should be unveiled in less than a month. Only four iPhone models have been unveiled thus far, each of which was a smashing hit for the company. We’ve no doubts the iPhone 5 will repeat the success even though it faces some tough competition.
