iPhone TIPS: 3GS Oleophobic Screen Coating Shows Burden of Wear?

Fellow German based blogger iFun.de reports about an iPhone 3GS owner is complaining about the burden of wear by playing a game. Flickfishing is a fishing game where the player must make intensive turn movements on the iPhone screen for hauling the fish line. He wrote the following:

Meine Anti-Fett-Beschichtung ist zum Teil nämlich schon weg, und das ist nicht nur merkbar, sondern auch auffällig gut zu sehen. Falls ihr euch wundert warum die Stelle so Kreisförmig ist, das ist die Stelle, auf der man beim Game “FlickFishing” (AppStore-Link) kurbelt”.

Basically it says: My anti-fat protection or oleophobic screen coating is already gone. I am not only notice that, I also can see it on my screen. If you are wondering why there is round spot, well that is the place in the "FlickFishing" I make the turn movements on the iPhone screen for hauling the fish line.

Q: How can I avoid those spots on my screen? A: To be honest since a long time I am using a screen protector to protect my both iPhone 2G and iPhone 3G. So I have no reason not to put a screen protector on my new iPhone 3GS as soon I get a hand on one. The screen protector I am using also prevents me from fingerprints and scratches. The big advantage of a screen protector is ofcourse you can remove them and stick a new one on it for just a few bucks! I wrote a review about those Invisible Shields by Zagg. shields months ago HERE. The condition of the Zagg shield on my iPhone 3G is still perfect, no spots no burden of wear, nothing. And yes I did also a lot of "FlickFishing"
