The anticipated comex’s jailbreak has been released as JailbreakMe 2.0. The wait has finally ended and iPhone 3GS can be jailbroken on iOS 4.0 or iOS 4.0.1 irrespective of old and new bootrom. JailbreakMe is an all in one untethered jailbreak for iPhone 4 3GS 3G and iPod Touch 3G 2G along with iPad. JailbreakMe 2.0 Jailbreak can liberate 4.0 or 4.0.1 iOS on any iPhone.

Caution: It is recommended to synchronize and backup your data using iTunes before employing JailbreakMe 2.0  After you have successfully executed JailbreakMe 2.0 Jailbreak, you should save SHSH Blobs to avoid future loss in case you update to a new firmware.

The following tutorial will aid you to carry out jailbreak iPhone 3GS with JailbreakMe 2.0.

Function 1: There are two possible firmware that are installed on iPhone 4 either iOS4 or iOS 4.0.1. JailbreakMe 2.0s both iOS4 and iOS 4.0.1.

Function 2: Visit JailbreakMe.com on your iPhone 3GS.

Function 3: Follow the instructions on website for iPhone 3GS Jailbreak.

Function 4: Let JailbreakMe 2.0 do the assigned duty and wait till it flaunts a message of Success.

Function 5: Gosh! You have a jailbroken iPhone 3GS [Old and New Bootrom] running on iOS4 or iOS 4.0.1.

For Unlockers: Bear in mind that JailbreakMe 2.0 is not an unlock for iPhone 3GS rather it is jailbreak iPhone 3GS. You can unlock iPhone 3GS on 4.0. or  4.0.1.

If you are an iPhone 4 user, you can follow the guide iPhone 4 Jailbreak while iPod Touch users should abide by this Jailbreak iPod Touch 4.0. Besides, the guide Jailbreak iPad 3.2.1 is also live.

Works perfectly for 3Gs MC136 3.1.3 Spirit JB

first restore and update to 4.0.1 with itunes 9.2.1
once restored activate with att sim or other hactivation
visit http://www.jailbreakme.com and slide to jailbreak
once done open cydia and install ultrasnow
after rebooting you can insert new sim and bingo you are done.

My MC 3Gs runs much faster with a restore and update rather than just updating to 4.0.1 from 3.1.3 Spirit JB.

You need an official Sim. Hacktivation is not supported in JailbreakMe

It is not possible without Official Sim

Flipout August 6, 2010 at 00:19

You will need an official sim card. You can buy a used one from ebay, I have bought one and am waiting for it to arrive.

You'll only need the sim card to access the browser for this jailbreak and then your one step away from using your iphone.

Question: I have a iPhone 4, firmware 1.59.00, OS 4.0.1. The phone has been activated with an AT&T sim. I am now overseas and would like to use Jailbreak and ultrasnow to use the iPhone with my local carrier.

As I do not have roaming for the AT&T sim, I have no service. I can connect to the internet using the wi-fi to browse to Safari to access the Jailbreak site. I would like to know if by performing this, would the phone lock up because I don't have a working AT&T sim. I have a new micro sim from my new carrier which I would like to use after the jailbreak and ultrasnow to unlock the sim. Should I proceed or wait?

I have the same problem. I jB fine with "Jailbreakme" my 3GS with 4.0.1 and then unlocked with utrasn0w 1.1-1 to use my vodafone card. Everything ok (even did a phone call). But then, a bit later it never gave me signal anymore. Installed the Hacktivation Patch, but still doesnt give me any signal!!
Help please…..

Turn off, take out the sim, turn on, turn off. Put the sim in, turn on and wait.
Worked for me.

I can’t get jailbreakme to work! Every time It seems like it loads 100% but then it says : oops… File received was invalid..I’m on 3GS 4.0.1 new bootroom. I know many people got this problem but the reason why I need help is because I’ve already jailbreaked one time before with JAILBREAKME before. My iPhone crashed and I restored it but I didn’t backupped it :( and now I keep trying but it won’t work. Doesn’t it work just because I’ve already done it one time with jailbreakme before I restored? Please reply. I got another question : when it don’t work for you guys (who hasn’t used this before) does it says oops.. File received was invalid (don’t remember what it said when I tried my first time)

EDO August 16, 2010 at 15:52

HI Frutten.

I got the same error you experienced.

I jailbreaked before my 3GS after update to 4.0.1 successfully.

after some days i decided to restore iOS 4.0.1 due to crash of springboard due (i suppose) to the contemporary presence of backgrounder and fast switching application.

After restore of factory defaults i tried three times jailbreak with jailbreakme.com but i receive the same messagge you got, and Safari now crash if I try to jailbreak again.

Please let me know if you find a solution !!!!

Hi

Edo

I have the 3GS, version 4.0.1 (8A306); firmware 05.13.04 and this tool works perfectly. Thanks for the awesome tool!

1) open your Safari and type in http://www.jailbreakme.com follow instructions.

2) ensure that your iPhone is connected to the internet via WiFi

3) opens Cydia —> Manage —> Sources —> and choose repo666.ultrasn0w.com and install it (confirm it too).

4) your phone should ask you to reboot, after reboot, it should be unlocked. My works fine on tmobile …. everything works!

Good luck folks!

My iphone 3GS (new bootrom) is currently jailbroken with firmware 3.1.2.

I'm going to update it to 4.0.1. Is Jailbreakme able to jailbreak my iphone 3GS new bootrom model MC133B, baseband 05.11.07? Are there any side-effects for jailbreaking it? E.g. loss of signal, apps won't install/work/keep crashing?

THANK YOU IN ADVANCE for ur replies~ (^_^)/

I have a question. Does jailbreakme only work for previously jailbroken phones or can it work for phones that have never been jailbroken before? I would like to know before I try this as I know that for some programs, it makes a difference. Please advise and thanks in advance for the help!

I bought one iPhone of model 3gs. At the moment I m using OS version 4.0.1 (8A306). When I got connected with iTunes it says a latest OS version 4.3.4 is available to update. I do not update this latest version OS on the hunch that I may loose all the data like phone no, pictures, video songs etc which are now loaded in the Iphone. Please advice.
