Please ensure first that you have the iPhone OS 3.1.2 installed as well as a 05.11.07 baseband. If you have the 5.12.01 baseband or higher though, unfortunately you cannot jailbreak yet. Meanwhile if your baseband is lower than the prescribed 05.11.07, you must first restore to the 3.1.2 firmware in order to proceed. Do this by starting up iTunes, selecting your iPhone from the device list, then holding down the option key and selecting restore. After this minor change, you can now push through with the tutorial.

Keep in mind, blackra1n only supports a tethered jailbreak. This simply means once you have successfully jailbroken your device, do NOT ever let your battery die. Anticipate it and charge immediately once you notice it signalling it’s on low. When you allow your device to die, you would still need to reconnect it to the computer and specifically use blackra1n simply to reboot it.
