I have two iPhones, one 3GS and the other is a 4. I try to search for files in documents in an app with my iPhone 4, there aren't any files in documents. It works fine for my 3GS but it doesn't show the files for the iPhone 4.
I am having the same issues as well. The files cannot be seen in my Iphone 4 and its really very troublesome to switch phones from time to time. Has anyone got a solution for this problem? I think it might be due to the app being buggy.
