These are instructions on how to jailbreak your iPhone 3GS on the iOS 5.0 firmware using RedSn0w for Mac.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please wait until we have posted a tutorial on how to update to iOS 5 using a custom ipsw if you need an unlock. The jailbreak is also tethered for all devices except the old bootrom iPhone 3GS which means you will need to connect your device to the computer each time you reboot. Finally, it may be prudent to save your SHSH Blobs by following this tutorial before continuing.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w 0.9.9b5 from here and place it in the Pwnage folder. Likewise, download the 5.0 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.0 firmware if you are already on iOS 5.0)

Extract the RedSn0w zip file by double clicking it.

Step Two: (Skip this step if you're on iOS 5 already)
Connect your iPhone to the computer and launch iTunes.

Select your iPhone from the list of devices on the left. Now hold down Option and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.

Navigate to the Pwnage folder on your desktop and select the 5.0 firmware ipsw. Click the Choose button to continue.

iTunes will now update your iPhone to the new firmware.

Step Three
Launch the redsn0w application from the redsn0w folder we extracted earlier.

Step Four
Once RedSn0w opens click the Jailbreak button

Step Five
Plug your iPhone into the computer and make sure its OFF then click the Next button

Step Six
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Seven
Your iPhone will now reboot

Step Eight
RedSn0w will prepare the jailbreak data.

Step Nine
Select Cydia from the list of options and click Next.

Step Ten
Your iPhone will now be rebooted again and RedSn0w will begin uploading the new RAM Disk and Kernel.

Step Eleven
Once this is complete you will be notified that RedSn0w is done. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.

BOOT TETHERED
Once you have jailbroken you will need to rerun redsn0w to boot tethered.

Step One
From the main RedSn0w menu click the Extras button.

Step Two
Select Just boot from the Extras menu to just boot tethered.

*As usual a big thanks to the iPhone Dev-Team and Geohot for their hard work and contribution to the iPhone community.

My 3gs is bricked after doing this... cant get out of reboot cycle... restore gives error 1601... redsnow justboot hangs at waiting to reboot.... Any worthwhile suggestions?

I tried to jailbreak to unlock my sim card. I have a 3gs old bothom, 5.0. I CANT jailbreak'it!!!!! Each time the same issue with all the versions of jailbreaks (5, 6 and now 7): "report failed" after the manipulation dfu. I don't know what to do... HELP!! ;)

you need to downgrade then to 4.1 (apple still signs the code signature for this version when saving shsh) or whatever version you know for sure you have shsh for. then you can jailbreak and flash the BB to 6.15 if needed. I will make a video of how to do this later today of how to downgrade using shsh w/6.15 installed (if you already have that installed). but really all you have to do is enter pwned dfu, restore with a stock ipsw (unless you have preserved BB then use ipsw with preserved BB), if 6.15 is installed you will get 1015, kick out of recovery with recboot.

I've got a 3GS w/5.13.04 BB on it. Just redsnowed to iOS5 with the preserved BB IPWS . Followed the tutorial steps, but now i'm unable to get Cydia (the app is not on it) so I can unlock it. Suggestions? thks

6italia0 - November 1, 2011 at 5:59pm

Restore again we/custom 5.0 and jailbreak without specifyiong .ipsw, I found that can actually tether an untetherable device. After that just do the ifile mod for mms and your iophone will be fully working (ifile mms mod is for 6.15 BB, gevey users and factory unlocked users 5.3.4 oree higher, works with 4.x and 5.x)

6italia0 - November 14, 2011 at 12:20pm

Meant to say 4.3.4

6italia0 - November 16, 2011 at 4:29pm

sometimes this happens and you need to specify the ipsw, but this may also tether your jailbreak for some odd reason. I had to do this to tether boot my iphone 4 a few times because I got the same error, but now I don't need to specify the ipsw anymore, all I have to do is "just boot" tethered

How to activate/hactivate iPhone 3GS with iOS 5.

6italia0 - October 26, 2011 at 2:14pm

put any live or dead at&t sim in and setup normally? I dont think you can hacktivate 5.0 but thats why I have like 100 old at&t cards lol

jaybot - October 19, 2011 at 7:59pm

I'm running jailbroken and unlocked 5.0 on a 3gs, and everything is running great, though find my iphone doesn't seem to be able to locate my iphone (though location services works fine in every other app). Anyone else having this issue?

The android community is all about helping and making the newst firmware available to your phone no matter what the manufacturer says/wants. The iphone community is exactly the other way. Tethered jalibreak? Mac only? Come on. Do you how many people have macs? You guys insult (or obeys) steve jobs' smartness. By the way i'm selling my iphone 4. Just bought a galaxy s II. Thanks dev team for making my choice way easier. Hope you break (again).

6italia0 - October 28, 2011 at 7:59pm

sorry to hear that, it must suck to have to use such a limited device. the only modification available for you is to root it to make it do only what other android devices do, but no actual mods (with an exception to astro). and so what if the dev team releases mac only software? they release the windows version usually within days and tehered isnt really that bad either (im using my iphone 4 factory unlocked 5.0 tethered), its not the worst thing in the world. But I still keep my two 3gs 32gb as backup incase I dont want to use tethered 5.0. But I guess if your ok with horrible oversize and zoomed in display and limited options then I guess thats what works for you

Is that really all there is to it because that'd be falbbegrasitng.

Kruelspell - October 13, 2011 at 2:19pm

Anyone can confirm this is untethered for the iPhone 3GS old bootrom?

2fix - October 15, 2011 at 6:49pm

I can confirm it is untethered. Reboots just fine. I just jailbroke my 3GS iOS5 with old Bootrom.

Kruelspell - October 15, 2011 at 7:20pm

Yes it is untethered for old bootrom 3gs but when it runs out of battery restarts fine plugin it to the power cord but it starts with a yellow screen instead of the battery icon. Anyone else having this issue? Or do i have to jailbreak again? (i was in 4.3.3 jailbreak before updating)

6italia0 - October 28, 2011 at 8:01pm

confirmed: two 3gs 32gb 5.0 05.13.04 and 06.15.00 untethered works great and no issues at all. (still, however, prefer to use my factory unlocked iphone 4 5.0 tethered though).

I think you hit a bulsleye there fellas!
