A great day for iPhone users because a new jailbreak version for ios4 has been released!
And its probably the most easiest jail break ever. Just go over to jailbreakme.com,
It then tells you, slide to jailbreak. It’s the same simple! It takes only 45 seconds.
Now you can even use apps that did not get approved on the Apple Store and find them instead on Cydia!.
This jailbreak works on all devices other than the first gen iPhone (metal back) and firmwares 3.1.2, 3.1.3, 4.0, and 4.0.1.
