Jay Freeman, the world know him with the name Saurik is the creator of Cydia. Cydia Store is an application similar to the App Store. Cydia Store can be used to replace the App Store in jailbroken devices running on the iOS.
In a recent video Saurik showed up Cydia Store running on the jailbroken iPhone 4 and he also talks about the Apple iPhone 4 Jailbreak.
You can checkout the video yourself, I am sure you’ll find that useful.
Here is the video of the iPhone 4 Jailbreak by Saurik :-
I guess this video will help out the iPhone 4 users to somehow understand how everything works, I am sure they will learn something interesting from this.
Thanx to Saurik for sharing out this amazing video and great ideas with all of us.
