So there's that option where you can encrypt your back up with a password. Thing is, I have never set up a password for it nor have I checked the box to encrypt it. It's so frustrating! Every password I know, I put in and it doesn't work?! any ideas? Please help!
I have read that I can look on keychain but I'm a pc. There was also something about restoring it & setting up as a new device but won't that erase everything? I don't want to loos my apps/info on my apps/calendars etc.
