In continuation to my "How to turn your iPhone 3G into an iPhone 4 (Battery Life)" post ,i will cover now methods of unlocking the functionality of the iPhone 4 on your 3G. The features unlocked are: Multitasking, Homescreen Wallpaper and Battery Life.

One of my favourite iPhone jailbreaking sites covers the jailbreaking process for the iPhone 3G and other. It has become fairly simple to do all of this so i'll spare you from reading instructions written by me and direct you to the post directly.

I have done all of the above and have had over a month's time to review the outcome. Sadly, things don't look good. The iPhone 3G even without jailbreak feel sluggish and god-awful with iOS 4. I wish Apple didn't give up on it so early and continued to develop great software on lower spec'd hardware for efficiency sake. Unfortunately, we live in a fast moving tech world and consumers must have the biggest and fastest at any price.

If you had to chose one thing to unlock that the iPhone 4 has is the Multitasking. Just make sure to keep an eye on the number of apps running. This can be a killer on resources. The outcome of this series of posts is not looking so great. The iPhone 3G really is starting to show its age and really lose its position of power among the Android (HTC Legend, Nexus One) and BlackBerry(Bold 8900, Storm 2) handsets in the mid-market segment.
