iPhone Dev-Team Releases Tethered Jailbreak for iOS 5

The iPhone Dev-Team has released a tethered jailbreak for iOS 5. Currently only the Mac version has been made available; however, the Windows version is coming soon.

With today's official iOS5 release, redsn0w has been updated to 0.9.9b5 to include the public URLs for the IPSW files. This way, first-time iOS5 jailbreakers don't need to supply the IPSW file manually. It's still a tethered jailbreak on all except the old-bootrom iPhone3GS, and it doesn't apply to iPad2 or the upcoming iPhone4S.

Because the jailbreak is currently only tethered for most devices, we're not going to release a new PwnageTool yet. Instead, we've decided to build some of PwnageTool's functionality into redsn0w (since you need redsn0w to "Just boot tethered" on every power cycle anyway). The new "Custom IPSW" button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now). Remember not to accidentally restore to the stock IPSW after you create the custom one! The custom one begins with NO_BB_ (for "no baseband").

You must enter "Pwned DFU" mode before trying to use the NO_BB_ IPSW with iTunes (and your hosts file cannot be pointing to Cydia's servers due to the new blob nonce mechanism they're using in iOS5).

Version 0.9.9b5 only available for Mac for now, until we can do more testing on the Windows version of "Custom IPSW".

We're currently working on a normal compatibility update for existing ultrasn0w unlockers. After that we'll try to fix the iBooks issue on jailbroken iOS5.

You can download RedSn0w 0.9.9b5 from here.

You can find our tutorials on how to jailbreak iOS 5 below:
● iPhone 4 (Mac)
● iPhone 3GS (Mac)
● iPhone - No Baseband Update (Mac)
● iPod Touch 4G (Mac)
● iPod Touch 3G (Mac)
● iPad 1 (Mac)

Hi dear friends I m using iPhone 4 v 4.3.3 and I like to change with iOS 5 pls advice me if it's good to me and also I can find on iOS 5 JB ?

no_ma'am - October 13, 2011 at 4:05pm

I think it would be best to wait for the 4gs to be released before releasing the untethered ios5. Just to be on the safe side. BTW, thank you DEV-Team for the time and effort.

Tico - October 13, 2011 at 11:18pm

I think he means released to the public...

6italia0 - October 13, 2011 at 9:37am

K so just tried to update my factory unlocked iphone to 5.0 with the NO_BB method and it says not eligible for build. I am on 4.3.3 with 4.3.3 shsh (reason I am using NO_BB method) and ive tried with modified host server and unmodified host server and got the same result both times. Anything I am missing? All I really want to do is update to 5.0 to see how it runs with the JB and then I am downgrading back to 4.3.3 because an untethered JB is more worth it to me.

Robot - October 13, 2011 at 2:25pm

Did you update iTunes?

6italia0 - October 14, 2011 at 7:13pm

Yep I've been running 10.5 for about 1 1/2 months too but updated after this post. I'm guessing the dev team still has a few bugs to fix, but I wonder if my old upgrade method would work, update stock and disconnect from iTunes 15 sec. After it says "restoring iPhone firmware" and using recboot. Worked on AT&T iPhone 4 4.0.2 to 4.1 and keeping 01.59.00

Robot - October 14, 2011 at 7:26pm

It can't be the beta iTunes 10.5

6italia0 - October 14, 2011 at 8:01pm

Ya I know, I updtated to official 10.5 already, I'm using mbp osx 10.7.2 w/10.5 itunes. Guess for now SDW:/

Robot - October 14, 2011 at 8:03pm

It can't be the beta iTunes

Robot - October 14, 2011 at 8:19pm

Sorry for the double post

kingcom - October 13, 2011 at 9:20am

thank you dev team. but it has a problem with seconds count. it's very slow, which lead to recovery mode instead of DFU mode.

MrEdofCourse - October 14, 2011 at 12:10am

I was having that problem too with the slow seconds count. What worked for me was to plug in and be turned off. Launch Redsnow and start the process, where the seconds count down. Hold down the Home button and then hold down the power button for a few seconds. Look closely at the iPhone, release the power button as soon as you see any sign of life on the iPhone, but keep the Home button held down until Redsnow advances to the next section and starts jailbreaking. Oddly, I can now reboot and remain jailbroken with my iPhone 3GS

Kenco - October 13, 2011 at 8:19am

No iPad 2 again. This sucks! I've been stuck on 4.3.5 (came with that) for months :(

kingcom - October 13, 2011 at 10:28am

upgrade it and enjoy ios 5 until its jailbreak released. do not stuck with 4.3.5 coz you won't get a jailbreak for it ever. :)

Robot - October 13, 2011 at 2:27pm

There is a tethered jailbreak for 4.3.5 not for 4.3.3

poop - October 13, 2011 at 3:58am

so the custom firmware feature is essentially a stock firmware without the baseband update? meaning that after restoring to the custom FW you still need to run redsn0w over it to JB it?

Karson - October 16, 2011 at 2:43am

You cuodln't pay me to ignore these posts!

A. Magdy - October 13, 2011 at 3:08am

The unlock is needed along with the jailbreak as well for users with the 06.15.00 baseband, please.

Tassilyn - October 16, 2011 at 2:45am

A good many vaaulbles you've given me.

Lorena - October 18, 2011 at 1:28am

Learning a ton from these neat airctles.

Tony - October 13, 2011 at 3:04am

Is the untether is going to be available soon ? Thank you

Noman - October 13, 2011 at 4:42am

Thats def important missing info - while most of us are wondering here that should i wait for untethered or not...

Jeff - October 13, 2011 at 9:52am

Agreed!.. I Travel and don't want to be tied to a Machine. ANYONE got a Clue or a site, Seems the DEV-TEAM Blog has not been updated..

barabba - October 13, 2011 at 11:32am

yep it would be very useful to know whether the untethered jb for ios5 is going to come out soon, if i remember correctly it was posted that they already found 5 exploits to jailbreak ios5, untethered. Now to know if the jb is already done and/or they're waiting for 4s release or what.
