picture 13 iPhone next generate OS 4.0 Preview

Apple this morning will give select members of the press a sneak preview of the next-generation iPhone operating system.

The event is scheduled for 10 a.m. PT at Apple headquarters.

The iPhone, iPod Touch, and iPad all run iPhone OS 3.0. Apple has not yet officially disclosed any details about iPhone OS 4, but a few rumors hint that a highlight feature will be enhanced multitasking. The current iPhone OS only allows a few core apps, such as iPod and Mail, to run in the background while another app is active.

A more recent rumor claims that iPhone OS 4 will debut Apple’s mobile advertising platform, which is corroborated by its $300 million acquisition of mobile advertising firm Quattro Wireless.

And perhaps more relevant to consumers, another last-minute rumor claims iPhone OS 4 will support printing from the iPad. (There is currently no native, systemwide printing feature for the iPad, though some third-party apps offer workarounds.)

Yours truly will be reporting live from the iPhone OS 4 event at Apple headquarters this morning. Stay tuned on this post for updates.

UPDATE 7:30 a.m. PT: Change of plans — rather than live blog, we’ll be posting a news report of the event. We’ll update this post as major announcements are made.
