JailbreakMe 3.0, just like version 2.0, allows easy jailbreak by simply pointing your device’s Safari browser to JailbreakMe.com, thanks to a PDF exploit in Safari.
This is by far the easiest way to jailbreak your iPhone 3GS, iPhone 4, iPod Touch 3, iPod Touch 4, iPad 1 and iPad 2 on iOS 4.3.3 without even having to connect it to your computer.
Step 1: Launch Safari and point it to http://jailbreakme.com.
Step 2: Tap on the “FREE”, followed by “INSTALL”. Only do this once, even if there’s slight delay in response time.
That’s it! The hack will now take advantage of an exploit in your browser to download the necessary files onto your device and execute a jailbreak script. Safari will close automatically and you should now see a Cydia icon on your Home Screen, with a download progress bar, just like when you’re downloading an app via Apps Store.
Once complete, you’ll get a pop-up notification letting you know that Cydia has been installed on your phone.
Kudos to @comex et al for another excellent jailbreak!
