When I first heard the term “oleophobic” I have to Google for the meaning and that is what I found, “describes the surface of a material not easily covered and actually launched an organic, non-polar oil” . So if the iPhone 3G-S is the introduction of an oleophobic coating is only one solution for the iPhone (and itouch’s) problems, dirty screens.

However, the coating can oleopohobic wear off when the phone is left in a warm weather for a long period. To ensure that the iPhone 3GS in a moderate temperature.
Yes, older Apple touch-screen have this problem. Although not a major problem in itself, but certainly annoys Apple owners. A simple phone call, touched your cheek fat or fat fingers, is used to touch the screen leaves greasy oil all over the place.
And now the iPhone 3G look after S, and we have Apple to thank.
How to clean your oleophobic coating? Apple state in their manual: just wipe your iPhone screen with a soft, lint-free cloth to remove oils left by your hands and face.
