Well I am not a very technical guy, but I have managed to jail break my iphone (3gs) and add a ton of programs. I have just gotten through changing all my sounds using winscp (unlock, keyboard etc etc.), so I guess I am not a complete idiot.
At one point early on I tried to update to the new firmware. I knew it was risky and of course it ruined everything (hopefully this will help at least one person that has used google search to try to find some answers)
Anyway, at that point it was easy to get back to where I was in the process. I now have over 250 apps and have all my settings where I like them and would like to have a safe backup. Since itunes has made it impossible to save multiple backups, or to even find where the backups are located, I am a little annoyed that I do not have a backup I can count on.
Well, what I have done is to copy the entire root file. If something gets messed up, do you think copying this back onto the iphone will immediately get me back to where I am when I make the backup?
I hope one of you more technical types here can confirm if this will work or if I should do something else.
