If you’re upset that your iPhone 3G is missing the coolest features of iOS 4—namely multitasking, screen orientation lock, and background wallpapers—you’re one quick and simple jailbreak away from enabling them. Here’s how it works.
Note: When iPhone 3G owners upgraded to iOS 4, a lot of us were faced with significant slowdowns and decided to downgrade back to 3.1.3.
