Jailbreak firmware 3.1.3 - Redsn0w

Less than a day since the release of the new firmware, as craftsmen have already found a way to jailbreak for it, not waiting for updates of popular programs.

So we need:

Run Redsn0w
Click on the Browse button and in the window that opens, select firmware 3.1.2 (3.1.2)

Next, click on the Next button and wait for the process to finish.

Select Cydia and click on Next (For iPhone 2G, we also select Activation )

Click on Next and monitor the line activity to put the phone into DFU mode

If everything is done correctly, the screen will first become white, and then a running pineapple will appear. After completion, you will only activate the phone in iTunes.
