PLEASE NOTE: This Jailbreak method is reported to work on iPad and iPhone 3G / 3GS 🙂 with iOS 3.2.1 / 4.0 / 4.0.1 🙂
Jailbreaking your iPhone 4 with any current version of iOS 4 is now as simple as going to a webpage in safari on the iPhone! Once jailbreaking and unlocking the iPhone became legal on july 27th 2010 it was only a mater of time before something like this was release, Get ready and give it a try for yourself 🙂
1: Connect your iPhone to your computer and back it up using the latest version of iTunes.
2: Open up safari on your iPhone and goto http://www.Jailbreakme.com
3: Slide the bar across the screen where it says Slide to Jailbreak.
4: Sit back and wait for your iPhone to be automatically jailbroken, It’s that easy!
Side Notes: The jailbreak download server has been flooded today for obvious reasons so give it a little time and try again if your jailbreak download or install fails, Also a few things to note it has been reported that some users are having an issue with FaceTime no longer working however mine appears to be fine it also needs to be noted that this can in fact brick your iphone (make it useless and no longer functioning) although this is very rare it has happened so proceed at your own risk!
