Apple states on its FQ2 earnings call (webcast, live blog) its conservative FQ3 guidance was partly due to a 2.6M Q/Q increase in iPhone channel inventory. Its strong FQ2 gross margin is attributed to lower commodity costs (i.e. cheaper flash memory) and product mix (more iPhones). Tim Cook adds Apple won't follow Microsoft's (MSFT) lead in offering "converged" PC/tablet devices. iTunes revenue was $1.9B, +35% Y/Y. China revenue rose over 3x to $7.9B. AAPL +7.1% AH.
