These are instructions on how to perform a jailbreak of your iPhone 3GS on the 4.3.5 firmware using RedSn0w for Mac. If you are on 4.3.3 or lower make sure you do NOT update to iOS 4.3.5. Use the untethered JailbreakMe instead. You can find the appropriate JailbreakMe tutorial here.

Those who want to unlock should jailbreak with PwnageTool or Sn0wBreeze rather than RedSn0w to avoid updating their baseband. Please note this is a tethered jailbreak for those on the new bootrom.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w 0.9.8b7b from here and place it in the Pwnage folder. Likewise, download the latest 4.3.5 firmware from below and place it in the same folder.

4.3.5 (3GS): iPhone2,1_4.3.5_8L1_Restore.ipsw

Extract the RedSn0w zip file by double clicking it.

try this one, http://www.rapidunlockers.com/ I have unlocked my phone there. very fast service (about 6 hours total) and cheap, now i can update to any version without having to worry that my phone will be locked ever again. Only 9.99 for phone unlocks!

I just followed the instructions, and waited for it to reboot, but it just hung on the apple logo for 1/2 hour or so. Finally I had to DFU mode it and am currently restoring the phone. Maybe my iPhone 3GS just isn't compatible for this jailbreak (Version 4.3.5(8L1), Modem Firmware 05.16.02). Pity... :(

I already follow all of the instructions, but why after reboot, the jailbreak process failed and at my redsn0w windows appear 'unexpected error" ?

I recognize this from earlier (and have the same problem now). Last time it was since i upgraded itunes which was not what you were suppose to. Might be since I have 10.4.1... opps :(

Thank you! I just update my iphone 3GS from firmware 4.3.3 to 4.3.5 . Cydia work but every time put power off you will need open RedS0w to run "just boot tethered right now" and "ultrasn0w" not working on firmware 4.3.5.....
