The new iPhone 7 and 7 Plus go on sale at Apple (NASDAQ:AAPL) stores and carrier retail locations in more than 25 countries today, with prices starting at $649. But this year, the company will not disclose opening weekend sales numbers because they are “determined more by supply than demand.” With strong handset pre-orders, Apple shares have so far gained 12% in what could be their best week since October 2011.
