Select the firmware ipsw we placed in the Pwnage folder on our desktop then click Open.

Step Six
Once the firmware has been verified click the Next button to continue.

Step Seven
RedSn0w will now prepare the jailbreak data

Step Eight
From this window you can select the jailbreak options you would like.

Verbose boot displays detailed information on boot of your device and is generally only needed by developers and advanced users.

Make sure Cydia is selected. For this tutorial we will also select Custom boot logo and Custom recovery logo.

When you click to select each custom logo option a dialog window will appear asking you to select the image. Locate the image you would like to use then press the Open button.

*Remember the rules for boot logos are: RGB or Grayscale format with Alpha channel and dimension below 320×480.

Notice that RedSn0w has already selected to Enable multitasking, Enable homescreen wallpaper, and Enable battery percentage. If you do not need multitasking we would recommend deselecting it as it makes your iPhone 3G run very slow.

Click the Next button to continue

Step Nine
Please plug your iPhone into the computer and make sure its OFF then click the Next button

Step Ten
RedSn0w will now guide you through the steps to get into DFU mode.

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 Eleven
Your iPhone will now reboot

Step Twelve
RedSn0w will then begin uploading the new RAM Disk and Kernel.

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

You can now unlock your device using UltraSn0w by following these instructions.

Jailbreak iPhone, iPod, iPad 3.1.3 with Any Version And MC Models

Spirit

What’s Spirit?
Spirit is an untethered jailbreak for iPad, iPhone, and iPod touch on the latest firmwares.
Spirit is not a carrier unlock.
If you currently are using a tethered jailbreak, you have to restore to use Spirit. Do not upgrade if you use an unlock on an iPhone 3G or 3GS. (You can, however, restore to 3.1.2 if you have SHSH blobs for that version.)
Requirements
Any iPad, iPhone, or iPod touch on firmware 3.1.2, 3.1.3, or 3.2.
An activated device: one not stuck on the Connect to iTunes or Emergency Call screen.
Any version of iTunes 9 (including 9.1.1).
Syncing with iTunes before trying this is highly recommended.
Note: On iPad, all this is still sort of beta. Some packages in Cydia, not designed for iPad, might screw up your system and require you to restore. Be careful. (And no, Cydia’s appearance is not final.)

Download Spirit:

Windows

Mac OS X

Other Stuff
Update (May 3): I’ve updated the jailbreak tool. It no longer deletes photos (sorry!) and should resolve the issue with error code c0000005. (If you still get that error with the new version, try setting compatibility mode to Windows 95.)
If you liked this jailbreak, I greatly appreciate donations:

Legal information.
Source code will be available after the inevitable update.
For troubleshooting purposes, here is a little program to read the syslog (which the spirit installer writes a bunch of stuff to). If you don’t know what this means, don’t bother.
Thanks to BigBoss, chpwn, chronic, MuscleNerd, OPK, planetbeing, pod2g, posixninja, saurik, westbaer, and anyone else whose name I have forgotten, for various contributions.
Plus, special thanks to everyone who donated to me in the past.
