You Can Enable Multitasking on the iPhone 3G
SourceTwitter 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. Its good to know youll be able to do it with the Apples official method, anyway.
