Comex et al (meaning Comex and the rest of the group) have finally released JailbreakMe which has to be the easiest way to jailbreak your new iPhone 4 running iOS 4 or iOS 4.0.1 update. Just like Blackra1n, all you have to do is slide (complete procedure below) and you jailbreak your iPhone 4.

JailbreakMe runs over the web and gets downloaded directly on your iPhone and then executes the jailbreak while residing inside your iPhone. Previously all Jailbreak tools operated from Operating Systems.

Here’s the detailed guide, even though it’s really easy to jailbreak but you can use this guide as an FAQ on jailbreak:

Step 1: Backing up your data

Quickly make a backup of all your important data (contacts, apps, photos, multimedia and calendar). This is not really required but highly recommended incase something goes wrong.

Step 2:

Are you on iOS 4.0/4.0.1? If not then Download it from our iOS download page. Make sure you have latest version of iTunes (version 9.2.1) before updating to the iOS 4.0/4.0.1

Proceed to the next step only when you have updated your iPhone 4 to iOS 4.0/4.0.1

Step 3: Go to

From your iPhone Safari mobile browser, go to and you will see this window:

Step 4: Slide and Jailbreak

Slide the bar at the bottom of the above page and the download will start. It’s recommended that you’re connected to WiFi because download will be a strain upon your 3G connection. Once you slide, download will start and it will automatically do the rest so all you have to do is sit back and watch.

Step 5: Your iPhone 4 is Jailbroken

Once downloaded and installed, this is the dialog box you should see on your iPhone to confirm that it is now jailbroken. Make sure you have Cydia running.
