Have question about cydia
Ok , so i bought my iphone 3GS yesterday , it came with 3.1.2 with a build date of the first week of december if that helps anything....
I then pluged in my iphone and jailbroke it , and left it on itunes, well came back to it updated to 3.1.3 with no jailbreak obveously ....
Anyways my question is when i was in cydia i chose the option for it to back up what ever was necessary for me to remain jailbroken if i accidentally upgraded.
So mainly my question is how do i access that information now ? and how do i use that to get back to 3.1.2 and rejailbroken
(forgive me if i am misunderstanding the option built into cydia... )
