If you have an iPhone 3GS with the new bootrom you will only be able to perform a tethered jailbreak at this time. This means you will need Redsn0w’s assistance to boot into your jailbroken device.
IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

These are instructions on how to jailbreak your iPhone using PwnageTool 4.1.2 for Mac OS X. If you need unlock and you have not updated to iOS 4 you will be able to preserve baseband and unlock iPhone using ultrasn0w.
This guide will work for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G, iPod Touch 4G, iPad and AppleTV. Just use the right firmware and select the right device (step four).
Step One
Make a folder called “Pwnage” on the desktop. Now you need to download there PwnageTool 4.1.2 from and iOS 4.1 firmware from .
When downloading the IPSW file, it is best to download it with Firefox since Safari often auto extracts it!
Step Two
Double click to mount PwnageTool then drag the PwnageTool icon into the Pwnage folder.
The iPhone DevTeam has just released jailbreak utility PwnageTool 4.1 for Mac OS X.
PwnageTool allows you to restore to a custom IPSW file. The main advantage of PwnageTool is for unlockers. It gives the ability to keep current baseband and preserve ultrasn0w unlock. This is only for those, who have not updated to iOS 4.1 by themseleves.
You can also add whatever packages you want in the “Expert” mode of PwnageTool, if you wish to pre-install something from Cydia.
The BlackSn0w Unlock utility by Geohot has been updated by MSFTGuy and PushFix to work with the latest firmware 3.1.3. However it works only with baseband 05.11.07 (!!!).
This modified version of BlackSn0w works for iPhones upgraded with PwnageTool or Sn0wbreeze, preserving the baseband version 05.11.07. Users who have updated to OS 3.1.3 by any other method have the 05.12.01 baseband so BlackSn0w and UltraSn0w will not work.
This new version of BlackSn0w will be very useful for iPhone 3GS OS 3.1.3 / Baseband 05.11.07 users who can’t downgrade to earlier versions but still need unlock.
According to iHackintosh, this new version also fixes a small bug making WiFi much more stable.
Blacksn0w RC2 will be available on ModMyi repo soon. If you don’t want to wait just add the source http://cydia.pushfix.info/ to Cydia and install it now.
Important: Blacksn0w for 3.1.3 is still in RC stage and there may be some issues or bugs. This is not an official update performed by Geohot, who has clearly indicated that he will not be updating any tools for the 3.1.3 firmware.
