Who updated the iPhone to firmware 3GS via iTunes 3.1.3 and had the jailbreak and unlock, ended up giving bad losing these benefits.
And later on Monday the Dev-team launched the release for the 3.1.3 firmware with PwnageTool 3:15 still only has a version for Mac - who has Pc will be waiting in the queue.
But who updated their iPhone 3Gs to 3.1.3 can be more peaceful because there is a way back to version 3.1.2.
Just follow the step-by-step following
1. Download the 3.1.2 firmware:
Firmware 3.1.2 iPhone 2G
Firmware 3.1.2 iPhone 3G
Firmware 3.1.2 iPhone 3GS
You may be using iTunes version 9.0.3.
2. Open and edit the hosts file on your computer:
C: \ Windows \ System32 \ drivers \ etc \ hosts (Windows)
or
/ etc / hosts (Mac OS X)
Add the following line:
74.208.10.249 gs.apple.com
With that iTunes will be thinking about communicating with Apple and the truth will be with the server from Cydia.
3) Connect the iPhone to the USB port and enter the DFU mode. ITunes will indicate that you need to restore your device, click ok and then hold down the ctrl or option click on Mac to restore to navigate your disk where this file with firmware 3.1.2 FW.
4) After finishing the restoration, you should see an error 1015. This is NORMAL. Your iPhone is in recovery mode now, and iTunes will say that a recovery is necessary. Again safety ctrl or option (Mac) click restore to get the firmware 3.1.2. This time do not need to enter in DFU mode.
5) After the restoration is complete you get another error 1015. This is NORMAL again. Just press OK and close iTunes.
6) Open the redsn0w version 0.9.4 and usually do the jailbreak.
7) After you finish the jailbreak the iPhone will reboot and voila, you did the downgrade to firmware 3.1.2.
