My question is about the applications.FlbKjZ folder? is this extension unique to my iphone 4 (I also have an applications folder without the extension in it that contains an exact copy of the one with the extension) Any changes I make to the apps inside these folders only work if I change things inside the one with the extension. Is this normal has anyone else seen this please enlighten me. The duplication exists for many other folders as well. none of the extension are the same but they all contain some variation of CAPITAL and lowercase letters as such: .FlbKjZ
