Fix your Hosts File for IPhone Downgrades
3.1.3 Users Advisory (Via Bigboss)
So to all your 3.1.3 3GS users that cant jailbreak, this is a reminder to you. Update your computer’s hosts file right now to point to Saurik’s server. This should be a permanent change everyone that owns a 3GS should make. This allows you to down grade your firmware in the future. Even if you don’t care about jailbreaking, it is still a good idea. What if Apple releases a firmware that you hate in the future? This at least allows you the option to downgrade. It also guarantees your SHSH is stored. While it’s unlikely 3.1.3 will ever be jailbroken since it is utterly worthless, it is still a good idea to get your SHSH stored. Once your hosts file is set up, anytime you restore, the signature is stored for you so that you can go back and restore to that firmware again in the future whether or not Apple decides you should or not. To fix your computer, simply follow these steps: OSX: Open the file /etc/hosts with a text editor. Windows: open the file C:\Windows\System32\drivers\etc\hosts with notepad: Add the line: 74.208.10.249 gs.apple.com Note: on windows you may need to “run as” administrator your notepad to get the file to save. On OSX, you may need to use sudo or su to get to root user.
