I believe I know the answer, but I wanted to verify....is something like Monster ScreenClean safe for the iPhone 3G S? I use it on my ACD, but I believe that using it on the iPhone 3G S would not be advised. Assuming my thinking is correct, is there a specific dry cloth you recommend to clean the iPhone screen? Right now I am using the Microfiber Wipe that came with my SwitchEasy Colors case. That should be OK, right? Thanks.
