Very newbie question
I've never JB'd, but i DID save my SHSH when i had ios3.1.3 on my phone a few weeks ago - just in case.
I read a guide where i can downgrade to 3.1.3 if i had uploaded my SHSH file to cydia's/saurik's server.
As i only have the SHSH stored on my hard drive, does this mean that i can't upload my SHSH file to cydia anymore, and therefore can't follow the guide to downgrade back to 3.1.3?
I am aware of a few posts explaining other ways to downgrade, but as i'm very newbie, i'd rather follow a detailed guide, because i don't want to make some error that puts my phone into some technical nightmare that i can't get it out of without help from the fine folks on this forum.
Thanks for any help!
