Shares of Apple (Nasdaq: AAPL), the world's most valuable technology company, set another record high and closed at a record $702.10, up 19 cents, as millions of global customers began to download the new iOS 6 from the Cupertino, Calif.-based electronics company.

Earlier, share set an all-time high of $703.99. Wednesday’s closing sets the company’s market capitalization at $658.2 billion, well ahead of Exxon Mobeil Corp.’s (NYSE: XOM) value of $418 billion.
