iPhone 3G S Oleophobic Screen Coating makes it Fingerprint-Resistant
We just heard that iPhone 3G S has a faster processor and double the RAM.
Some folks who have been digging through Apple's iPhone 3G S tech specification page have stumbled upon another nice but minor change.
iPhone 3G S screen will come with a fingerprint-resistant oleophobic coating, something that is missing in earlier iPhones.


Fingerprint smudges on the iPhone's screen have been a minor but frequent complaint from users. Being a touch screen device, Apple's iPhone has always had a problem where greasy fingers would leave fingerprints on the screen. It also accumulates natural skin oils while making a phone call as the screen frequently gets pressed against your cheek. Although, the fingerprints and oil-marks are not very noticeable (due to the ambient light sensors), they become easily visible when the iPhone is kept in a slightly tilted position or is looked at from a distance.

As iPhone 3G S Oleophobic (Oleo means Oil) screen coating will prevent any fingerprint marks or smudges from sticking on the screen.

The cleaning instructions for iPhone 3G also differ from that of the iPhone 3G S. The iPhone 3G screen-cleaning requires users to use "soft, slightly damp, lint-free cloth" but for iPhone 3G S screen, a dry clean cloth is all that is needed. This simplifies the cleaning process and reduces the moisture related damages, which used to happen due to the usage of a moist piece of cloth.
I personally don't use any screen cover on my iPhone 3G and the way I clean my iPhone 3G is by wiping it off my t-shirt. But I agree that a fingerprint riddled iPhone screen is not a pleasing site so its nice to see Apple giving iPhone 3GS screen an oleophobic coating to address a minor annoyance.
