Will Apple force me to upgrade to OS 4.0 if I restore?

    I currently have a jailbroken 3GS running on 3.1.3 and I'm satisfied with it. If I want to restore the phone, will iTunes force me to upgrade to 4.0 or will I still keep my 3.1.3? I've heard of 4.0 causing problems (especially on 3GS and 3G models) so I'd rather not upgrade to it.

    Yes it will. Don't do it.! Go to www.iclarified.com and search for firmware 3.1.3 firmware for the iPhone 3GS and use that one to restore.

    So when I hit the restore button, will it prompt me with a window saying either choose a firmware to restore with or will it automatically do 4.0?

    Unless you have your SHSH blobs backed up already (it's too late now, the signing window is closed), then any future restores will be to 4.0 or above.

    I think you have to hold shift then click restore, but I'm not sure.
