Jobs details iPhone OS 4 (photos)

Steve Jobs takes the stage at Apple headquarters in Cupertino, Calif., to give a preview of iPhone OS 4, which will be available later this summer.

Giving guests and the media a preview of the iPhone OS 4 software set to be released this summer, Steve Jobs, Phil Schiller, and Scott Forstall took the stage Thursday at Apple headquarters to show off a few of the 100 new features.

The updated software will most notably allow apps to run in the background, without any slowing of performance, Apple said. Multitasking will not be available on the iPhone 3G because of hardware constraints, and Jobs conceded, "We weren't the first to this party, but we're going to be the best." At the end of the morning, during the question-and-answer period, Jobs added, "If you need to use a task manager, you're doing it wrong."
