L'iPhone Dev-Team ha rilasciato un untethered jailbreak per iOS 4.3.1. Il jailbreak implementa l'exploit untether distribuito da i0n1c.

L'exploit untether 4.3.1 ci è stato cortesemente concesso da Stefan Esser (@i0n1c su twitter), un ricercatore specializzato in sicurezza della Germania. Stefan ha molta esperienza riguardo alle vulnerabilità, e ironicamente parlando, il suo primo contributo per la community del jailbreak per iPhone è stata proprio la sicurezza migliorata — lo scorso anno ha battuto Apple implementando l'ASLR per gli iPhone Jailbreakkati con il suo "antid0te" framework. Siamo allora felici di vedere che Stefan abbia portato le sue attenzioni su un exploit unthetered per iPhone!

I dispositivi supportati sono: iPhone 4, iPhone 3GS, iPod touch 4G, iPod touch 3G, iPad 1 and Apple TV 2. L'iPad 2 non è ancora supportato.

Puoi scaricare RedSnow o PwnageTool per effettuare il jailbreak. I link per il download sono elencati sotto:
● RedSn0w (Windows, Mac)
● PwnageTool (Mac)

Pubblicheremo più tutorial per mostrare come effettuare il jailbreak.

I Tutorial:
● iPhone 4 (Windows, Mac)
● iPhone 3GS (Mac)

IMPORTANTE: Gli utenti di Ultrasn0w non devono aggiornare! L'iPhone Dev-Team necessita di più tempo per rilasciare un aggiornamento ad ultrasn0w per il firmware 4.3.1.

Abbiamo bisogno di rilasciare un aggiornamento ad ultrasn0w prima; che risolve alcune incompatibilità quando il firmware 4.3.1 viene usato sulle vecchie baseband supportate da ultrasn0w. E ricordate che finché non rilasceremo il fix di ultrasn0w per il FW 4.3.1 (lo annunceremo qui e su twitter), dovrete effettuare il jailbreak solamente tramite un firmware personalizzato (custom IPSW) da PwnageTool, Sn0wbreeze oppure xpwn! Non provate ad effettuare il restore o l'aggiornamento ad un firmware originale, altrimenti perderete lo sblocco!

Ahmed Irushad - April 6, 2011 at 5:22pm

dev team, can you please release an unlock for iphone 4 ( baseband 02.10.04 & up ) i am waiting for that almost a year, and many more are still waiting for that, i know you guys can do it, i appreciate your work & i am grateful for that...

Steve J - April 6, 2011 at 3:49pm

hei dev team - who needs the jailbreak if 2/3 of iphone 4's are locked in some pointless network.

Chrystal - April 6, 2011 at 1:50pm

Hi There, I'm using redsnow to jailbreak my ipod touch 3g, I followed all the steps, but it always stop at the "uploading ramdisk" step, then the downloading jailbreak data disappears the ipod reboots and still isn't jailbroken while on my pc it is still uploading the ramdisk. Am I doing something wrong?

Hi there, If I toggle the vibrate switch to silent mode, the iPhone is supposed to vibrate as we all know. However, since Jailbreaking, it doesn't always vibrate, and sometimes vibrates when I switch it back to the normal position, when it shouldn't. I restored the phone to pre-jailbreak and it works fine so its definitely a software related issue. Has anyone else noticed this? What could be causing it? Everything else works fine. Thanks in advance.

Tomster88 - April 6, 2011 at 5:09pm

I noticed that too. I have the same issue. I also notice this jailbreak, or maybe it's 4.3.1, is making my phone sluggish.. have you noticed anything like that too?

DAJ721 - May 12, 2011 at 8:54pm

I have the same issue... What can I do?

Martin - April 6, 2011 at 12:09pm

Does this work on the iPhone 3G? (Says only 3Gs in the title)

Noise - April 6, 2011 at 12:36pm

It doesn't. 4.3 and 4.3.1 do don't support iPhone 3, only iPhone 3GS and iPhone 4.

Monty09 - April 6, 2011 at 7:41am

jailbreak went perfect on ipod touch 4th gen however once in cydia and i was adding everything i always add i randomly got a white flash then it went to apple logo with loading bar but my screen with cydia was underneath...? and it let me keep using cydia so i exited and resprung the winterboard and it went a way.... just thought it was really weird. but thansk to the devs!

Mi Bear - April 6, 2011 at 6:40am

I also would like to thank the dev team for saving us from the restricted world of Apple :) Can you please write some info on the ipad2 jailbreak? if there is a timeline or hope for it thanks

Z!GGY - April 6, 2011 at 1:58am

Macki - April 5, 2011 at 5:48pm

Thank You dev team for this! and of course i0n1c :) Without the jailbreaks I would never buy the Apple products, It's like the missing part:) Im still wondering why we are not getting any information on the IPad 2 jailbreak? Is Comex going to release the IPad 2 4.3 jailbreak, it couldn't be too hard for him just to twitter saying if he will, and if it's coming soon or something like that :/

Maxi - April 5, 2011 at 8:05am

Work for 3.10.01? thank's.

coolio - April 5, 2011 at 5:42am

I had some troubles with Redsn0w jailbreaking.. so had to use the pwnage tool to make custom IPSW. But now my 3GS is up and running perfectly.. thanks dev-Team and everyone behind it.

Jay - April 5, 2011 at 12:53am

So does this mean the unlock is right around the corner for 4.3?

Rez - April 4, 2011 at 11:28pm

Just jailbroken my 3GS with new redsnow, I lost my network and Internet , any help

Steve - April 4, 2011 at 11:49pm

Me 2 , 3GS, no phone number shows in General settings,, Carrier softbank, cannot send SMS ,

Rez - April 5, 2011 at 12:29am

I couldn't access my setting menu either, tried online for a solution with no luck so I had to restore my iPhone and forget about jailbreak.

Joe N - April 5, 2011 at 12:41am

Just JB my iphone 4 and lost Network as well. Bars are at 1. Any info?

ss ss - April 5, 2011 at 12:47am

YEah mine is the same bars at 1 always. No Carrier, phone number, no sms on 3gs

Joe N - April 5, 2011 at 2:51pm

So what I basically did was restore the phone back to 4.3.1 (Itunes/Tiny) and re-jailbroke it with Redsnow. Everything works perfectly now. I get my carrier back, I can make calls, sends SMS/MMS and so on. The only "bug" that I notice is that the reception bars remain @ 1. I've noticed it doesn't affect reception what so ever, just more of a "bug" that displays 1 bar.

Zeljko - April 5, 2011 at 5:33pm

that could be mine comment 2. cheers.

rudolf - April 6, 2011 at 9:56am

Restored to 4.3.1 via iTunes using TinyUmbrella to keep my baseband at 01.59.00 and then JB it using Redsn0w (repeated the whole procedure twice). Signal bar shows one bar or at times no bars at all. Turning OFF an On airplane mode, 3G and Cellular settings did not help. I did not install Ultrasn0w. I keep my baseband at 01.59.00 just in case I travel abroad and want to use my cell with different carrier.

Dogter - April 4, 2011 at 11:10pm

Just updated both my iPad 1 and iPhone 3Gs to iOS 4.3.1 and jailbroke with the info provided. So far no issues Since my phone was out of space it would not let me update my OS. Even Cydia would not let me update Cydia APPs due to lack of space. I had to do a restore install of iOS 4.3.1 and reinstall all of my APPs, settings, music, photos, ex. Doing a complete restore ended up freeing about 3 gigs of space

Dogter - April 4, 2011 at 11:12pm

I meant 2 gigs, not 3. Typing in the dark so I hit the wrong key. After restoring and doing a clean install 4.3.1, the JB went through with no issues

Carlos de Carvalho - April 4, 2011 at 10:01pm

Amazing !!!!!!!! Thanks a lot !!!! Looking foward for the ipad 2 version, any news !?!?!

Sam - April 4, 2011 at 10:20pm

It's out now!!! Just JB'd mine and it's sooo much better....or was it a dream?

Carlos de Carvalho - April 4, 2011 at 10:42pm

HOW !!!!!!!!!!!!?????????

rok - April 4, 2011 at 8:24pm

works fine thanks

iNo3L - April 4, 2011 at 3:43pm

Wanna say Thank to Dev Team for the hard work on Untethered JB on 4.3.1...did anyone had a issue after JB ur iP4 had no carrier network on PwnageTool 4.3? Then i tried JB on Redsn0w then i turn off 3g (i dont know if effect) and its work out fine.....Thanks again Dev Team for your Fabulous Piece Of Art..

asdfsd_croat - April 5, 2011 at 3:02am

happend to me BUT then i did another restore then it worked... after RESTORING ipsw from iTunes turn on your phone, enter sim pin and wait for network to initialize...then power off and do the redsnow procedure...then it worked...first time i skipped that initialization
