The redsn0w 0.9.4 doesn't recognize 3.1.3. So what I did is: - in iTunes, put 3.1.3 to the phone - use redsn0w 0.9.3, browser-> load in iphone OS 3.1.2, then follow the rest ... everything works.

Go to this link: You can download them from here. Save them to the desktop file pwnage as designated.

I have a 2G iPhone that im trying to unlock, when i follow the instruction and get to itunes it takes me to the invalid sim card. Any suggestions on how to get around it????
hibiscus - April 15, 2010 at 8:41pm
I got the same message on my iphone when i unlocked it. all i did was continue on with the instructions and everything worked fine once it was all said and done

Hi everyone, i have a question, hope you can help me. I have a 2G Iphone that i jailbroke with Pwnage tool to get firmware 2.2 and it works fine. I was wondering if i can i use this method to upgrade it to firmware 3 without leaving it unjailbroken or messing up the baseband? Thanks!

Yes you can. but you have use windows xp.

I unlocked my phone using the RedSn0w, everything worked perfectly. But the volume is very very low, I can barely hear the other person. I tried to download a volume patch through Cydia, but the one with the drill icon won't download, says something about size being mismatched. I tried downloading one for the 2.0 version, it download and says installed, but there's no difference. Does anyone know how to fix this? Thanks
lily - February 3, 2010 at 4:35am
I'm stuck in step 2. When I open my iTunes, the restore screen doesn't come out. A box came out and says that my sim card is not compatible. What should I do? Help !!
Christy - February 6, 2010 at 1:59am
I think if you have a fresh phone that's never been used, you can skip Step two (b/c iTunes won't connect to the phone since you don't have an AT&T sim in it). Just go straight to step 3. Hope this helps.
Christy - February 2, 2010 at 10:47pm
I unlocked the phone successfully following the steps, but cannot get connected to the internet. It shows I'm connected to my wifi at home and the little blue internet icon (the little blue fan shaped icon on the top of the screen) is on, but when I try to open Cydia or Safari, it shows there's no internet connection. Can anyone help me with this? Thanks!
Christy - February 2, 2010 at 10:54pm
nvm--i put in a sim card and all of a sudden the internet is connecting...does anyone know why though? isn't the wifi network independent from the phone service carrier (i'm not subscribed to internet use thru my phone plan)?

Does Redsnow work on iTunes 9?
hibiscus - April 15, 2010 at 8:32pm
Yes it does. I just went through this process and it worked! If it says your sim is not for the right carrier, just keep going with the process and everything will work fine at the end.

I'm not quite sure how to say this; you made it exretmely easy for me!
Eric - January 10, 2010 at 6:24pm
I am trying to jailbreak/unlock iPhone using this guide.. But the phone isn't activated! I have everything I need to do this but I don't know how I can go about upgrading the firmware for this device without activating the phone..
Eric - January 10, 2010 at 7:54pm
Had to enter DFU mode and restored the FW manually.
Andrew - January 22, 2010 at 2:46pm
How did you restore the framework manually?
Jamie - December 29, 2009 at 10:25pm
The links aren't working... but found the downloads on
Christine - December 28, 2009 at 8:54pm
I downloaded the 3.1 firmware but it comes as a zipped file instead of ipsw, so I tried downloading the 3.0 version and it's the samething. When I tried to unzip it, it's just a bunch of weird files and a couple of folders and there's nothing with the whate square iTunes logo like the one show in the tutorial pics. Can anyone help me with this? Thanks!
ReleX - December 29, 2009 at 7:32am
You have to save it as .ipsw instead of zip. Right click on the link, then in the end of the name, write .ipsw and then click "download" or "OK" or whatever it says.
maria - December 29, 2009 at 4:20pm
i hat the same problem and i tried to save as ipsw instead of zip but it didn't work so i installed mozilla and worked
Christine - December 30, 2009 at 4:13am
Sorry I'm being slow (not a computer savy person), but when I right click on the link like you said, it just comes up with the normal options such as Open, Open in New Tab, etc, I don't see where I can type in '.ipsw' in place of 'zip'. When I click on the Download option from the right clicked option list, it still doesn't give me option to replace 'zip'. Can you elaborate on how to download this as a ipsw file? Thanks!

I have now successfully made all the steps. All things worked fine. However, i discovered you can't use the 3.0.1 version when using vista, go with the 3.0 instead. I'm having problem launching cydia. Yesterday, when i used the guide, no problems what so ever using cydia afterwards. Today, i was going to install some stuff using Cydia. When I tapped the icon, it started to load as usual, then a message pops up saying some files are missing and are not up to date then i pressed OK, then it shut down to springboard. Now, when tapping the Cydia icon, it says "Loading Data", ´then shuts down to the springboard. What could be wrong? Also, I checked the "Icy" box when using Redsn0w, so I have both Cydia and Icy. I installed the Mobileterminal via Icy, but Terminal won't start either. It just shuts down and goes back to springboard. Will the Icy app interrupt Cydia or what? Please Help :)

hey.well i upgraded and jailbreak my iphone before using these steps on iclarified and it worked. now mh i was having some problems with the iphone and i thought to give it a restore ...shift+restore and all the steps by the book but it didn't jailbreak after the redsn0w step i have on the screen that image with the usb cable and itunes and sais that introduce a sim card so..i do....then unlock it....i unlock it ....i can see on left up that the sim is working but the fron screen never changes and i cand use my iphone the only thing i can to is slide the bar for emergency call....:| ??? what can i do? i taken the step fron redsn0w program again and again but no use.... please can some one help me?
ReleX - December 28, 2009 at 1:15pm
did you use the 3.0 version or the 3.0.1? I had the same problem with the 3.0.1. I'm using vista. Had to put it in DFU mode. Then I did all stuff from the beginning usin the 3.0 version instead of the 3.0.1. Also, I didn't have a SIM-card in the phone.

maria - December 29, 2009 at 4:10pm

maria - December 29, 2009 at 4:18pm
well the problem is that i can't do the step again form the begining because the itunse dosen't open the iphone only after i insert a valid sim i can't do the restore starting itunes and i've tried to retake the step when it get's to the part withredsnow over and over again and also with quickpwn but this one it says that it's not compatible:| and i had the sim card in the phone
Ryan - December 19, 2009 at 11:08pm
Redsnow works fine, until it says updating kernal, then the programs crashes and windows is trying to find a solution. Any help?

James - December 8, 2009 at 6:43am
i did this and it worked. i mean it got jailbreaked but when i open it the only thing that show up is an itunes logo and at the bottom is a firewire cord of apple. meaning connect it to the itunes. but it shows up again that's why i just restored it with the one i downloaded here. is it normal? what are the stuff i can do to fix it?
maria - December 29, 2009 at 4:32pm
i have the same problem...that means that the redsn0w didn't jailbreak your iphone you only upgraded or restore and it only works with "valid" sim card.... the 1st time i jailbreak my iphone i had this problem so i did it again but with more attention on those hold the button for 3 ,10,30 seconds and some how it worked then i had no plb restoring or upgrading the iphone but know i don't know i also had the problem but it's something wrong at the redsn0w step cause it doesn't recognise the right firmware:|
XPIKY28 - December 7, 2009 at 1:10pm
I have a iPhone 2G with a non working power/sleep/hold button, the one on the top and I want to jailbreak/unlock it with Pwange Tool 3.1.4, but how can I put it into DFU mode with out using that button? Pwange Tool 3.1.4 requires to put in DFU mode, I am open to use another program like Redsnow too have both Mac and PC..
Noob - January 29, 2010 at 4:08am
Fix the button. Had the same problem, tried to work around it for 2 days. If you use another app to put the phone in DFU redsnow looses the connection and you have to start all over. It's easyer to just fix the button
MTaylor - November 25, 2009 at 11:57am
everything was working great until i tried to open the restore file in redsn0w. it keeps saying "Unable to recognized specified IPSW." any suggestions.?
maria - December 29, 2009 at 4:37pm
yep i have the same problem and i tried over and over diffrent links to download the same version but it still didn't recognise it so i tried an older version? and somehow it recognise it?( i resored the 3.1 and it recognise only 3.0??? wierd) but at the end it still doesn't jailbreak:|
slim - November 23, 2009 at 2:35am

I am updating my phone directly from 1.14 firmware to 3.0, now I have the problem that the redsnow finished, but the phone is given me a blue screen and never rebooted, please help, what should do.

Alban - October 27, 2009 at 7:11pm
Hi all. I've done everything "by the book" last night and everything worked well, except my battery life was much shorter. Anyone experienced the same problem? Also, my phone freezes and became quite slow. Any suggestion? Thanx in advance.
Andrew - October 31, 2009 at 8:29am
I cant download the 3.6 .bin file thing it says its not on the site anymore any help please my email is
Longfellow - October 26, 2009 at 2:12pm
I can't receive calls/texts anymore after doing this. I've tried switching out the SIM, re-doing the whole unlock process, power off/on - nothing works. If it means downgrading then please lemme know how, hit me at thanks
Daniel - October 26, 2009 at 5:39pm
Hey, My problem was that I was using the wrong IPSW for the jailbreak/unlock. My advise is to try to use pwnage if you have a Mac available.
micah - November 4, 2009 at 3:11am
Same problem here. I can't receive calls on 3.0, I have tried to do it many times with doing backup or not, but no luck. Also RedSn0w can't recognize the 3.0.1 IPSW file. I see that many people now have the same problem.
Daniel - October 23, 2009 at 4:13am
Hi, Itunes 9 is complaining about the IPSW files being unvalid. Anyone had this problem?
nad123 - November 4, 2009 at 1:03pm
I have the same problem, did you fix yours. Appreciate any input on the matter. Thanks, nadia
Fahmy - December 21, 2009 at 4:16pm
I have the ame problem here, seems that itunes 9 dosen't work with this. looking for a reply from the i-dev or iclarified team !!!! is it true ? is there a work around ?

Hi.. I recently jailbreaked my iPhone 2g to 3.0.. But now I try to activate the wi-fi function and it doesn't work.. Could someone please help me?

Is there an update for this that I can use with OS 3.1.......I have a 2G iphone, windows, and iphone OS 3.1, but can't seem to find out how to unlock please.
Aaron - October 14, 2009 at 10:48pm
Just ran the 3.0.1 update. Needed 3.0.1 for step 2; 3.0 for the redsn0w application. Outside of that, nothing to it!
