These are instructions on how to jailbreak and unlock your iPhone 3G and 3GS using BlackRa1n and BlackSn0w for Windows.

These instructions will work with the 3.1.2 firmware, the 05.11.07 baseband, and iPhones which require hactivation. If you have already jailbroken following these instructions to unlock 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 on 5.12.01 or higher, unfortunately you CANNOT jailbreak as of yet. If your baseband is lower than 05.11.07 then you must restore to the 3.1.2 firmware for the iPhone 3G or 3GS. You can do this by opening iTunes, selecting your iPhone from the list of devices on the left, then hold down the Shift key and click Restore.

You can find the Mac version of this tutorial here. Ok lets begin...
