Step 4. Open iTunes and wait for it to tell you that its in restore mode.

Note: firmware might be downloaded as iPhone1,2_3.1.2_7D11_Restore.ipsw.zip depending on your browser. Make sure you delete the .zip so that it is recognized as an ipsw. Do not try to extract the file. Google: show folder extensions, so that you are able to edit the file extensions.

Sep 5. Hold shift+restore and point to the 3.1.2 firmware.

After the restore has finished; activate via itunes first only if you have AT&T, if not run blackra1n first.

Now that we are on 3.1.2 follow these instructions:

go to www.blackra1n.com

click on the logo that corresponds to the operating system you are running, either a mac or pc.

once you have blackra1n on your desktop, connect your iPhone via USB and make sure you exit out from iTunes.

run blackra1n, iPhone should restart and a logo of George Hotz, the creator of blackra1n, will appear. Your iPhone should reboot properly and now blackra1n will be on your home screen.

You must have a data plan with at&t or access to wifi to continue.

A new icon is now on your home screen of your iPhone, blackra1n. Click on it and a window with three options will appear. Cydia, Sn0w and Rock. Install Cydia and Sn0w ONLY. Rock is very buggy and can mess with your iphone.

*if you were on 3.1.3 before, Sn0w won't work.

After a succesful installation, you will also have cydia on your home screen.

Congrats, you are now Jailbroken.
