How to Jailbreak iPhone 4, iPhone 3GS with iOS Version 4.3.5 Using Redsn0w.
Warning: Jailbreak at your own risk. Please exercise caution and read the comments, as these jailbreak instructions are not guaranteed to work.
Note: If you would like to jailbreak any other iPhone version, visit my comprehensive iPhone Jailbreak guide.
This tutorial contains jailbreak instructions for both Windows and Mac users, using Redsn0w. As of August 1, 2011, it is necessary to revert back to the iOS version 4.3.4 when jailbreaking, as explained in this tutorial.
Warning: This is a tethered jailbreak, which means that you will need to redo the jailbreak each time your iPhone reboots (you will not lose your data each time.)
Windows & Mac Users
- iPhone 4 or iPhone 3GS
- Firmware: 4.3.5 (check your version in Settings » General » About)
- iTunes 10.4
- Download iOS 4.3.4 IPSW (iPhone 4 (GSM) or iPhone 3GS)
- Download Redsn0w 0.9.8b3 (Windows or Mac)
1. Open Redsn0w, click Browse and select the iOS 4.3.4 file that you previously downloaded.
2. Click Install Cydia and hit Next.
3. With your iPhone off and the USB cable plugged in, click Next.
4. Follow the on-screen instructions to put your iPhone in DFU mode. Your iPhone will restart and be fully jailbroken.
5. Note: This is a tethered jailbreak, meaning you will have to redo the jailbreak each time that you reboot your iPhone. To do so, simply click the “Just Boot Tethered Right Now” option in Redsn0w.
Was your jailbreak successful? Please post questions and suggestions in the comments.

Hi I want to jailbrake my phone but my firmwall isn’t 4.3.5 it’s 04.11.08 so what does thy mean?
Hey your firmwall is actually your firmware, which is something different. They mean your version. The version that they are jailbreaking here is the iOS version 4.3.5. It doesn’t mean anything.
I want to jailbreak for my 4.3.5

I just updated it 2 5.0 and I can break it so if I follow your instuctions will this work
Works perfectly 😀
cydia becomes to a blank icon….how to fix it?
It DIDN’t Do nothing, screen everything worked
my phone is blocked an i used this program to jail break it
an it didnt WORK!
cant make calls still
took 2 hrs off my time downloading programs and for what?
i cant even get APPs. or use my phone.
Yeah mine worked but my cydia icon is blank and wont open? any solution?
Yea I’m confused I’ve never done this before , my firmware is 4.10.01 not 4.3.5 is that gonna muff it up ? I can’t afford to ruin my phone
okay so i did this whole process,I even watched a video so i can do it the same. and i did i did everything i was suppose to. and when it got done all my screen shows is the i tunes logo and the usb connecting to it. what am i suppose to do
I tried this twice, the first time a pineapple appeared on y screen but then showed the connect the itunes image. when trying the second time it said downloading jailbreak data and then displayed connect to itunes. how do i get past this?
This happened to mine too. Im trying it again, but with no response from the “power” or “home” buttons I’m worried. If anyone can tell us what’s going wrong, please, this is apparently not a one-hit tragedy.
some program still cann’t be open, n Cydia cann’t open too..
I installed it but cydia seem to net be there its only a blank icon and will not open, how do i fix this?
I tried to downgrade to 4.3.3 and I must of did something wrong, so i tried to restore it back to 4.3.5 and not even jailbreak my phone anymore, and its not even letting me restore so i can use my phone PLEASE SOMEONE HELP ME
Did not work for me. Upon installation of software the reboot doesn’t work and leaves the phone with the apple logo.
is it possible to do this unteathered if so how and please email me the answer if you will (firstname.lastname@example.org)
I downloaded it and everything worked, but anytime I would try to change something you have to restart your phone, I did that and it wouldnt get passed the apple when your phone starts up, any help figuring this out?
Seemed to work, but Cydia won’t open.
yeah cydia won’t open to me either what can i do?
My iphone 4 ios 4.3.5 crashed after the jailbreak… Can i restore back to the original system that before jailbreak? And after i restore can i jailbreak again?
well i did the jailbreak worked got tons of free apps and games BUT in order to use the iphone as a phone. I needed to reset it to factory settings as for some reason the jailbreak conflicts with my telus sim card any thoughts on working around this? i want to use it as a phone and application device not one or the other.
Worked great…… ( i think lol) despite having the latest IOS 4.3.5 which people have claimed to have problems with.
In the process of installing new features now.
guys for those carrying 4,3.5 firmware ! i prefer waiting a complete jb software not tethered one! i know jb make i phone the best smartphone in the market but note that the current softwares cant do permanent jb, every time you reboot or switch off your ip you need to restore jb process !! i think lets wait for a month from now and our redsnow team will find a solution for this 🙂
Is it safe? My iPhone 4 is version 4.3.5 and I never jailbreak before…
yes and no,
am having this version in my ip, i did jail break via redsnow and it was pretty good 🙂 but there is smthn you should know with version 4.3.5 you need to do restore your jailbreak 🙂 boot tethered ! so you can say it safe when you maintain your phone on, once its off you need to boot tethered everytime. for that i restored my ip and ill never jb it again 🙂
yes its safe BUT if you have a sim card in it it may conflict and wont get a signal for phone service:( like it did with me i got it installed lots of games and apps but couldnt make a call or send a text cause it didnt recognize it as a phone. removed jailbreak and it works as a phone but my apps and games erased
I just have a pineapple in the centre of the screen. Any thoughts?
if your ip stucked either on apple icon or in pineapple one you just need to do the following:
1- press power and home bottoms togather, then your phone went off.
2- open your itune in your computer, then connect your ip to the usb.
3- directly after connection press on the power bottom for three seconds then pree on home bottom (keep pressing the power too) for 10 seconds then release the power bottom and keep pressing on home bottom then for 15 secds, then i tune will recoginze your mobile and will do restoring 🙂
hope you did backup b4 jailbreaking 🙂 good luck any question dot hesitate to ask me via email@example.com
i jailbroke it using ineedjailbreak and i got cydia on my phone but it wont open any solutions???
i want complete jailbreak on my phone . but how i can do that ???? 🙁
isn’t the current iOS supposed to be 4.3.5, but the download is 4.3.4
because the latest one will not let you jailbreak
didnt work. icons have disappeared, like Settings! No Cydia icon. wtf
Hi, Just a quick question. I’ve never done a jailbreak before and I need to know what it means by rejailbreak everytime it reboots. Does that mean if your phone runs out of battery and you turn it back on, you need to re-do these steps again? So everytime the phone loses power or you turn it off, it is deemed useless untill you connect it back up again?
it works well! great thanks
I’ve watched every video on Youtube and I did everything 5 times so far. I tried 0.9.8b3 and 0.9.8b4 along with the iso 4.3.4 and it installs just fine but after opening up cydia it deletes my settings on my phone. I tried to install installous but it never shows up. and to top it all off when I turn my phone off it will never restart. It goes into recovery mode and then gives me error code 1013. I went into my settings and fixed the code but still cant get it to work. I have jailbroken my phone before and had the same problem but found out i was using the wrong software. this time i made sure. thanks
The same with me … 🙁
hello i need some help i did everything but my iphne still working
