Did a search and didn't see anything specifically for the back of the ip4. I'm not a screen protector user for the front as I've never had any issues and usually have the phone screen facing in with a seido holster. But I'm going to spring for a screen protector for the back of it. I am currently just using the one that came with the phone and I cut off the little tab at the bottom. It's actually pretty functional, but doesn't have the cutout for the camera/flash. So what's a good but cheapie screen protector for the back but that has the cutouts for the camera/flash?
