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 latest 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 not please update your firmware to 3.1.2 using iTunes before continuing.
