    After the launch of the iPhone 3G it was inevitable that the 2G iPhones were soon to be abandoned, but no one ever imagined that it was going to be so quick. Within a short span of time after the release of 3.1.3 firmware for the iPhone 2G, Apple decided not to support iPhone 2G any longer. With this news out in the market, several iPhone 2G users like me were disappointed.

    However, recently it came to my notice that there was someone out there working hard so that iPhone 2 users could enjoy most of the features available in the new 4.2.1 firmware that was only made available to iPhone 3G, 3Gs and iPhone 4 users. Well, I tried and it really worked out. I could also now enjoy the same features like multitasking, iPhone 4 quality wallpapers, video recording application, set home screen wallpapers, set lock screen wallpapers, organize apps into folders and several other features. The best part being that all these features were available for both jailbroken and activated iPhones.

    In order to update your iPhone 2G to support 4.2.1 firmware features, continue reading the steps below.
