Jailbreak iPhone 3G/3GS New Bootrom On iOS 4.0 And 4.0.1 With JailbreakMe

So you’ve got an iPhone 3G or 3GS with the new bootrom from Apple and are looking for a way to jailbreak your device easily after upgrading it to iOS 4.0 or 4.0.1? We’ve got some good news for you! You can now very easily jailbreak your iPhone using a new tool called JailbreakMe and as you will shortly find out, this is the easiest method of jailbreaking any iOS device so far. For more information, our complete guide and the relevent links, continue reading after the break.

First a little introduction about this method – with a significant contribution from the famous iPhone Dev Team, iPhone hacker Comex has released the JailbreakMe tool and it’s so remarkably easy and simple to jailbreak your iPhone with it that a simpler method simply can’t be made. All it basically requires you to do is visit the tool’s website from your phone’s Safari browser, and follow the on-screen instructions. No downloads required, no PC connection required, no custom firmware making required, no need to run any tools on your computer, no need to meddle with putting your iPhone into DFU or download mode first. It really is as simple as a one-click-root on Android.

The only catch to jailbreaking with this tool is that it doesn’t work on the old bootrom and requires you to have the new one on your iPhone. If you are not sure about your bootrom, you can still go ahead and give it a shot. At the most, if your bootrom isn’t compatible, it won’t get jailbroken.

Excited about it by reading the details and can’t wait to get on with jailbreaking your iPhone 3G or 3GS? Here are the step by step instructions on jailbreaking your iPhone 3GS on iOS 4.0 and iOs 4.0.1 with JailbreakMe.

    I restored to 4.0.1 on my 3GS, but I cannot get past the screen where it says the SIM card is not supported – hence cannot go to jailbreakme.com over WiFi in step 3 – any suggestions?
