Redsn0w 0.8 iPhone 3.0 jailbreak (3GS, Windows)

[maXimus]

This guide works for 3.0.1. Just restore to 3.0.1 using iTunes, then point redsn0w to the 3.0 ipsw and NOT the 3.0.1 ipsw.

This guide is for jailbreaking your iPhone 3GS running 3.0. It is being written with the 0.8 release of redsn0w. In the event that redsn0w is updated, you can still use this guide provided there are no major changes to the procedure. If there are major changes, I will write another guide. You can check out the release thread for more information.


What you need before beginning:

1. iPhone 3GS 3.0 firmware


*If you have previously updated or restored with 3.0, you can pull the file from one of the following locations:

• XP: C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Updates
• Vista or 7: C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates

2. redsn0w 0.8


Notes:
1. After jailbreaking, you must use ultrasn0w to unlock.
2. I always recommend you do a fresh restore before beginning although it's not a requirement.
