Jailbreak iPhone 4 step by step

[uzairrrr]

JailbreakMe is the latest jailbreak method for all devices running iOS 3.1.2 or newer. Like I said before, JailbreakMe is the easiest jailbreak you will ever find but some of you asked me to write a tutorial about it.
This guide and tutorial will show you how to use JailbreakMe to jailbreak your iPhone. Obviously, most people won’t need this tutorial because JailbreakMe is pretty straightforward.
Step 1: Make you your iPhone is backed up in iTunes, in case something goes wrong.
Step 2: From you iPhone, go to JailbreakMe.com.
Step 3: Slide to jailbreak.

Step 4: Sit back, relax. JailbreakMe will be downloaded to your iPhone and will work its magic. When done, a pop up will tell you that Cydia has been installed.

Step 5: Reboot your iPhone. You don’t have to, but it’s always a good thing to do.
That’s it. Nothing to download to your computer.
