Apple Inc has set another company record - the tech giant said today it sold 1.7 million iPhone 4s in the first three days they were available, according to dpa. The smartphone hit stores Thursday with queues forming outside Apple and AT&T stores and workers turned away some customers because the phone is in such high demand. "This is the most successful launch in Apple's history," said chief executive Steve Jobs of the sales figures through Saturday. The smartphone is now sold in the US for between 199 dollars and 299 dollars, depending on the model. Those in Britain, France, Germany and Japan can also purchase the phone and 18 more countries will be added to the iPhone empire by the end of July.
