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.


By the market close, Apple hadn’t announced numbers about downloads. The company has scheduled initial shipments of the iPhone 5 for Friday after announcing 2 million preorders in the first two hours of availability last week. The company said they’ll be available in 249 U.S. retail stores on Friday.
