If Apple announces multitasking for its iPhone and iPad tomorrow, it will be a limited version that the company controls, allowing some applications to run in the background but denying others, experts said today.

On Thursday, Apple will roll out iPhone OS 4.0 in a presentation to reporters and analysts at its Cupertino, Calif. headquarters. Most industry watchers expect that Apple will add multitasking -- the ability to run multiple programs simultaneously -- to the mobile operating system.

"The iPhone OS has push notification, but that's not the same," said Aaron Vronko, the CEO of Rapid Repair, a company that services and supplies parts for do-it-yourself iPod, iPhone and iPad repairs. Vronko was referring to the half-hearted form of multitasking Apple added to iPhone OS 3.0 in March 2009. In push notification, the iPhone pings Apple's servers to see if there are, for example, new messages waiting for an instant message client. Push consumes some battery power, but much less than true multi-app processing, Apple claimed at the time.
