If you are sick and tired of having to wipe all the fingerprints and smudge marks from your iPhone screen, you’ll be thrilled to know that the new iPhone 3G S will have a “Oil Repellent Screen”.
You can find more about this on the iPhone How-to page on the page about cleaning your iPhone. “…If your iPhone has an oleophobic coating on the screen (iPhone 3G S only), simply wipe your iPhone’s screen with a soft, lint-free cloth to remove oil left by your hands and face.”
Here’s to no more streaks! More here at Apple
