So far Apple has only announced push notification support in the upcoming iPhone 3.0 OS to support building apps that at least can listen for messages in the background. Now Silicon Alley Insider kicked off a slew of new rumors (see also Daring Fireball and TechCrunch ) by saying that Apple is trying to get real background app support for 3rd party iPhone applications on the iPhone.
The background app support might even come as early as iPhone OS 3.0. Back in February rumors of iPhone background App support first surfaced. It would surprise me if it does as the beta versions of the iPhone 3.0 OS do not have this feature yet as far as we know.
Real background app support in the iPhone would take away the biggest advantage of the Palm Pre. Apple always argued that background apps take too much battery and RAM is also an issue. The rumored new iPhone 2009 might solve at least that problem with doubling the RAM.
