iPhone delays Apple OS

Apple fans will have to wait four extra months for the commercial launch of a much anticipated product: OS X. Apple needed to dedicate some engineers and quality testers from its OS X team to its iPhone project, which shows how crucial Apple views its mobile phone project. As a result, only a beta version of the next Apple OS will be ready by its originally scheduled June launch date at the Worldwide Developers Conference, with a commercial launch to follow in October.
