Hi, At the Apple Store today, when they were applying the Power Support film to my 3GS, the Apple rep used iKlear to clean off my 3GS screen before applying. First, I didn't realize that you should use cleaners like that on the 3GS. Is that normal? Second, is Monster ScreenClean a safe alternative to iKlear for the 3GS? I have some Monster at home and that way I wouldn't need to go out and buy iKlear. Thanks.
