Generator Research, a research company predicts that the iPhone market share will continue to rise and in the near future will reach about 40 percent, while Nokia will drop from its current 40 percent to 20 percent by 2013.

According to the company’s report, by 2011 Apple and Nokia will become even in mark share holdings, Generator Research also points out that by then Apple will have sold over 77 million iPhones.

In an interview with Mobile Today, Mark Loughran, Nokia UK general manager said that “the iPhone seems to have the same design and color, upgrading from a sub-standard two megapixel camera to a still low 3.2 megapixel camera, and is probably a disappointment for many people given the high tariff and lifetime ownership costs.”

In any case, iPhone’s recent launch brought Apple over one million handsets sold in just three days. We will see how the market evolves in the next years, such predictions do not take in account other manufacturers plans. Perhaps we will have a real iPhone killer.
