hi, i just got the 4s a couple days ago and i went to clean the screen today(it had some grease on it). I took a 100% cotton t shirt and wet the corner down a bit with some water from the sink. i then just wiped the screen gently with the damp side and dried it with the dry side. i was reading around and it seems like this is apple's suggested method for cleaning iphone screens, im just worried because it seems like the screen isnt as smooth as it was before and it kind of attracts fingerprints more. do you think i could have screwed the oleophobic coating up, or am i just being ocd? thanks for your help.
