I realize this is the wrong section, but no one posts in the jailbreak forum. So I just have a quick question. I'm running 3.1.3 on my 3gs that I jb'd with spirit. I can't use pwntool to upgrade to 4.0 because I can't use iTunes 9.2 because of the spirit userland...thing. SO, if my 3gs has the old bootrom and I restore to 3.1.2 and jb with blackra1n, could I then use pwntool to upgrade to 4.0? I just wanna make sure that will work before I actually do it.

Thanks for the help!
