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.

whats awesome is this is an untethered jailbreak already for 3gs 5.0, some of you probably are thinking "bulshit". But to prove this check out my videos http://www.youtube.com/watch?v=Y_vl7Li8iYA http://www.youtube.com/watch?v=Rz3Jd5Lou-I

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.
