Hi all, I've had a screen protector on my iPhone 4S since the day I bought it. I've gone through about 5 Zagg InvisiShield protectors and I'm plagued by problems, so I'm about to order a set of Power Support Crystals. I had a few questions about the screen's oleophobic coating. Does installing and then removing a screen protector wear out the oleophobic coating? Also, for those of you out there that are screen protectorless, how long have you had your iPhone and does the screen do a good job with fingerprints? My old 3GS started fingerprinting real easily after just about 3-4 months. And, I plan on going screen protectorless for the next few days while I make the transition. I hope nothing happens to the coating and that the screen doesn't get scratched in just a week or two. Thanks!
