How to Jailbreak and Unlock Your iPhone 3G, 3GS Using BlackSn0w [Mac]Posted by admin
These are instructions on how to jailbreak and unlock your iPhone 3G and 3GS using BlackRa1n and BlackSn0w for Mac.
These instructions will work with the latest 3.1.2 firmware, the 05.11.07 baseband, and iPhones which require hactivation. If you have already jailbroken following these instructions will be easier.
For those with a new iPhone 3GS (updated Bootrom), BlackRa1n only supports a tethered jailbreak. This means that once jailbroken you should not let your battery die. If it does die you will need to reconnect it to the computer and use BlackRa1n to boot it.
Before continuing make sure you are on the 05.11.07 baseband by following this tutorial. If you are not please update your firmware to 3.1.2 using iTunes before continuing.
You can find the Windows version of this tutorial here. Ok lets begin…Step One
Open your web browser of choice and navigate to http://www.blackra1n.com. Click the Applelogo at the bottom of the screen.
If you chose to unlock device using blacksn0w you will be presented with a Post Install log for sn0w. CommCenter will be restarted and there is no need to reboot. If your carrier doesn’t support 3G then disable it. Press the Close button to continue.
