HTC continued on its warpath toward becoming the No. 4 smartphone vendor in the world last month as the company recorded record revenue of NT$45 billion ($1.55 billion USD) in June. This marks the third straight month that the Taiwan-based mobile giant saw revenue hit a new high, and it was up 10.9% over May. HTC’s second-quarter revenue totalled NT$124.3 billion ($4.2 billion USD), topping the company’s earlier projection of NT$120 billion, and growing 19.43% over the first quarter of 2011. HTC has not yet reported its full earnings for the month of June, but analysts estimate that the company shipped 11.6 million smartphones in the second quarter, bringing first-half shipment totals to roughly 21 million units.
