Apple said it won't release Leopard, the next version of the Mac operating system, in early June as planned, blaming the delay on the iPhone.
Apple said that it borrowed some key software engineering and quality assurance resources from its OS X team in order to keep the iPhone on track to ship in June. As a result, the company won't release Leopard as planned at its Worldwide Developers Conference, taking place June 11-15 in San Francisco.
Instead, Apple will show off a near-final version at the conference in early June and give developers there a beta copy to take home with them. The final version of Leopard should ship in October.
The iPhone contains "the most sophisticated software ever shipped on a mobile device, and finishing it on time has not come without a price," Apple said in a statement.
While unconfirmed rumors recently had the iPhone shipping June 11, Apple now says it will ship in late June.
Apple announced the iPhone earlier this year, unleashing a frenzy of anticipation among end users and competitors in the mobile phone sector. The phone will come with a touch screen and a music player.
