I just picked up a white 3G and I'm going to get an invisible shield; I've put them on every iPod I've owned so far and they've worked like a charm. However, I don't really want to put anything on the screen - I mistakenly put the shield on the front of my iPod touch and have never liked the texture/drag it has. So, before I decide to ruin my beautiful iPhone's screen, I'm wondering if anyone here has ever had an issue with a 'naked' screen. After all, Apple does call it scratch-resistant glass... Thanks in advance fellas.
