Apple celebrated record quarterly revenues and unit sales during its third quarter of 2010 despite poor economic conditions. It sold 3.3 million iPads between April and June 2010 and 8.4 million iPhones during the quarter. While some had criticized the iPhone 4's antenna, it sold over 3 million units by July 2010 with a low 1.7% return rate. Apple executives said they were working to balance supply and demand for iPads and iPhones. Some analysts projected nearly 12 million iPad sales by the end of 2010, while others were concerned about future growth once early adopters purchased iPads.
