How long does Oleophobic Screen last?

I've had my 3GS since the day after it was released. I have relatively no issues with "fingerprints" on the display.

Hope this helps.

I just bought a new 3GS phone for 2 days. I discover that the screen is free from finger prints whereas the black rear case is full of finger prints. It seems the new oleophobic coating is really workable. I have not bought any screen protector yet but I ask myself what is the point to buy it. The screen protector must deteriorate some degree of touch screen performance. However, I am doubt how long a coating can last! Can some experienced users share usage experience with me. Thanks!

I have had my 3GS since Sept 2009. I gets some heavy use (but careful and not roughly handled) and sometimes with sweaty fingers when I am in the gym and use my iPhone 3GS in a sports armband. The finger marks wipe off just has easy as they did on day one.

The Oleophobic screen coating should last a while, and I would be very surprised if it wore off within 12 months or even longer come to mention it. Every day touch screen use should mean the coating should last for years in my opinion.
