Few hours ago, @comex, an iPhone hacker, has annouced a browser-based jailbreak tool for jailbreaking iPhone 4 running iOS 4/4.0.1. The tool should also work with older models of iPhone including iPhone 3GS, 3G and the original iPhone. Added to that, you can also use the tool to jailbreak iPad and iPod touch.
This is the simplest jailbreak tool you have ever used. No download is required. All you have to do is to launch Safari on your iPhone and point it to http://www.jailbreakme.com. Just slide the “slide to jailbreak” slider to kick off the jailbreak.
Early adopters mentioned the tool does work perfectly. But some reported the jailbreak tool affects Facetime and MMS on iPhone 4. Comex and the rest of iPhone development team are looking into issue. It is expected the issues will be fixed very soon.
If you have problems accessing the jailbreakme.com, you can also use the alternative link: http://jailbreakme.modmyi.com.
As reported earlier, the Library of Congress has made iPhone jailbreaking legal but Apple said it will still void your warranty. So, use it at your own risk.
I will further post a detailed jailbreak guide in the upcoming post. Stay tuned.
Update #1: You can check out the step-by-step guide for jailbreaking procedures using JailbreakMe.
Update #2: The Facetime and MMS bugs are fixed by the dev team.
Tested on a 3G iPhone and works perfectly. Will be testing on a 3GS next.
just jailbroke my iphone 4 and love it
hi simon, pls let me know if my 3gs jailbroken via spirit, can use this jailbreakme.com to jailbreak 4.0.1?
@irene,
No problem. You can restore/upgrade the iPhone to 4.0.1 and jailbreak it using jailbreakme.com
does it create cydia…..?
@Mady,
Cydia is installed automatically after jailbreak.
i am trying to jailbreak it on a 3G, but it keeps crashing on me.
i synced it before i tried it, just like the site told me to.
any ideas?
If you crash to purple clouds it may be due to server overload. Reboot and try again.
3.1.2 blackra1n new 3gs boot / upgraded to 4.0.1 and this works. But lots have mentioned restore to default first then restore apps after JB as needed.
It totally disregarded blackra1n JB and did fresh jailbreakme patch.
How about cydia and unlock for 3Gs OS4?,,,
Worked perfectly on my 3GS. It adds Cydia to the home screen as well.
Just now tested on a iPod (OS 4), it’s OK.
I’ve a question, a i have a 3gs jb with 4.0, to do another jb with de new version of OS 4.0.1 i have to update then jailbreak again with this webiste/app?

@omar,
You need an official sim card or phonebook sim card to activate the iPhone before you can use jailbreakme.
has anyone else noticed massive battery life loss since jailbreaking?
