HTC posted impressive second-quarter results on Friday noting that its profit of NT$17.52 billion was up 104% year-over-year and up 19% over the first quarter. The Taiwanese phone maker’s shipment total of 12.1 million devices during the quarter was up 24% year-over-year and 25% quarter-over-quarter. The company also noted that it shipped a total of 21.8 million devices during the first half of the year, a big jump from the 8.7 million it shipped during the first half of 2010. HTC noted that much of its growth came from the Americas, Europe and Asia. The average selling price of an HTC smartphone is currently $349, down from the average price of $359 last quarter thanks to new entry-level handsets. HTC expects its third quarter revenue to jump 10% quarter-over-quarter and 90% year-over-year, and plans to sell “around” 13.5 million handsets.
