Please help with Restore to 3.13
I have an Iphone 3gs that was running 3.13. I have iTunes 9.1. The phone was never jailbroken. I want to jailbreak it and unlock it. The problem is I am now stuck on the restore screen in iTunes and it won't accept a restore to 3.13 presumably because it wants me to download the new version of iTunes and get 4.0 os.
To prepare it to sell, I did the dumb thing of clearing all data on the phone itself by going into the general setting area. I then tried to do the spirit jailbreak. But the phone went to the Apple logo and froze up.
Now I can't get it back to just running 3.13. Any help with this would be much appreciated. Am I out of luck since I didn't back up any 3.13 files?
Also, is it all relevant that I have another iPhone 3gs that is running 3.13 that is jailbroken.
Any help is appreciated.
