You Can Enable Multitasking on the iPhone 3G

Twitter user @cdevwill, the same guy who posted the screenshots of Cydia running on the iPad some days ago, has found out that by editing a single preference file, the N82AP.plist to be exact, you can set the multitasking value to “TRUE” and enjoy your new multitasking iPhone 3G. Of course, this implies that you have to have root access to your iPhone OS through jailbreak.

After all, we knew that multitasking is possible on the 3G, just because apps like ProSwitcher from Cydia work just fine on the 3G. It’s good to know you’ll be able to do it with the Apple’s official method, anyway.

I don't agree that this means apple will officially support it - they've already announced they won't. Consumers won't be going into any files and changing the multitasking value to “TRUE”.

The title of this thread is "YOU can enable multitasking on the iPhone 3G", no one said Apple was going to support it.

Nobody said the title of this thread wasn't "You Can Enable Multitasking on the iPhone 3G".

No need to be nasty huh?
You were saying that you didn't think Apple was going to support it but no one even implied that, again, the title says that YOU can enable it, not Apple.

Very interesting, but I would imagine that they might make it a bit more difficult to do in the final version. I would expect them to remove the multi-tasking APIs from the final 3G firmware (there would be no need of them...)

Friends with 3g have enabled multitasking, and they report no significant performance loss.

Another artificial limit imposed by Apple.

EDIT: As pointed out by JasonBot and Ungrateful Ninja, this is impossible, and I was mislead.

Your friends have not really "multi-tasked" as there are no apps yet out that take advantage of the new APIs. All your friends have done is use the new saved states and the new quick-launch toolbar. The features use no resources. It won't be possible to get an idea of performance until they run several background processes at once.

To be clear, I am not saying that Apple is right (I suspect that it is, in fact, an artificial limitation). I am merely saying that your friends haven't disproved it until they've actually used it.

Are you kidding?! My 3G doesnt have enough memory to even remember the number of the song i left off on in shuffle, what makes you think that multitasking on the 3G would function well at all....:rolleyes:

My mistake. Thats why there was no performance loss :D

At the iPhone hacks section.
It might be possible once 4.0 is JB.
Also there is a few people that have already JB 4.0 betas thru various methods so its not impossible and like they stated not that hard to enable it on 3G iphones.

Sure, it's not surprising you'll be able to enable it if jailbroken, but don't expect performance to be that great. This doesn't change the fact the the 3g is severely short on RAM, so while you may be able to stream audio in the background, I wouldn't expect much more. It's not like you are going to be able to run a Nav app in the background while playing music or web browsing, and I'm sure this is why Apple isn't giving the 3g full support.
