Restoring JB'n 3GS on 3.0

[theman510]

I've sold my 3GS on ebay and will be restoring it before sending it off to the winning bidder. If I restore, will it force me to upgrade the firmware? It's currently on 3.0. I'm leaving it up to the buyer to decide but want to make sure it's something I can do. I'd like to restore it, but leave it on 3.0; or at least give him that option.

Thanks

If you have SHSH's saved you can restore. If not, then it will force you to get iOS4. Apple has stopped signing anything older than iOS4.

Ok I have them saved. So I just plug into itunes and hit restore? Or is there some backdoor way I would need to do?

This guide should help
Gives you the info on how to set your hosts file so it looks at Saurik's server instead of Apple's, allowing you to use the saved SHSH. Of course just use whatever IPSW that corresponds with the saved SHSH you have

Thanks a lot! that looks awesome. I am assuming it's pretty similar for using mac OSX?

Yep, a quick search with google should find you an exact copy except for OSX, the most important part is just changing your hosts file and using the correct IPSW that matches what SHSH you have backed up with Saurik.
