In April, Apple's (AAPL) Chinese sales crushed expectations, and helped deliver a strong EPS beat in spite of slowing U.S. iPhone sales. Could China come to the rescue again today? China's 3G base rose 118% Y/Y in June to 176M subs, and smartphone growth has been torrid. Also possibly helping Apple: strong iPad sales (tablet forecasts have been rising) and a margin boost from low flash memory prices. On the flip side, Europe may have been weak, and MacBook sales soft ahead of a June refresh.
