According to the latest survey regarding the mobile phone market issued by IDC, Nokia is still the leader with a market share of 37%. During the second quarter of 2007 the Finnish company has shipped 100.8 million units equaling more than those of the next three vendors combined.

According to IDC's Worldwide Quarterly Mobile Phone Tracker, much of Nokia's growth was attributed to its shipment growth within Europe and Asia, but still showed some signs of struggle in North America.

Tough the big winner of the 2Q 2007 is Samsung who “stole” the second sport from Motorola, Following multiple quarters of increased growth.

In the second quarter, the South Korean company has shipped 37.4 million units. Samsung’s success is due to its Ultra Edition phones and recent release of Ultra Special devices, but the company also had an increase in the emerging markets.

With only 35.5 million units sold, Motorola is now on the third place and was the only vendor to post a year-on-year decrease among the leading vendors.

The fourth and fifth places belong to Sony Ericsson with 24.9 million units and LG Electronics with 19.1 million units.

Sony Ericsson's Walkman line of phones accounted for a third of its shipments in the second quarter, and the company announced two new Walkman-branded handsets, the W960 and the W910, both expected to ship later this year.

Overall, in the second quarter, the vendors shipped a total of 272.7 million units worldwide, 16.5% more than the same quarter a year ago.

IDC said that the big story of the quarter is Apple’s iPhone, which was launched on June 29. "Even though limited in the number of units shipped, the iPhone is likely to have a disproportionately large impact on the industry. For one, it has pushed the envelope on industrial design and user interfaces for all vendors. For another, it could forever alter the structural relationship between device vendors and mobile operators who have traditionally controlled the mobile environment, especially in the US.” said Shiv K. Bakhshi, Ph.D., director of worldwide mobile device research at IDC.
