Ever since the release of Apple's iPhone sales have been beyond what anyone could have ever hoped for. Estimates now have Apple having:
8% of all mobile phone revenue and a whopping 32% of the industry's handset profits.
Since these estimates only consider the first two quarters of the year 2009, the sales were shown to drop off towards the time of the announcement of the new iPhone and the estimates just barely take into account the rush of sales from the release of the newest iPhone, the iPhone 3GS. Estimates towards the end of the year would show the full effects of the release of the new iPhone.
The real question is, how did Apple, a nobody in the smartphone market, over take the Goliaths of the market with a product that is only 3 generations old?

formidable smartphone ecosystem, which history suggests is very difficult to overcome
