Multi-tasking Can Be Enabled in iPhone 3G

Twitter-user named @cdevwill claims multi-tasking can be enabled on the iPhone 3G (and that means it can be used for every device with iPhone OS 3) just by setting a TRUE-flag in the capabilities list.

Some people are not surprised of this, because obviously Apple turned this function off to increase the battery line. But the way of turning multi-tasking on looks way too simple, don't you think?
