Hi. I take my iPhone to school and I have a Speck Pixelskin HD + a screen protector on it. However, the screen (or screen protector) just seems to get scratched. I don't know how; the pocket I keep it in only has my Apple in-ear headphones in (inside the triangle holder - no metal exposed) and my tiny paper school diary. Yet, the screen just keeps getting scratched and I'm spending a small fortune in new protectors! So I'm looking for a case to cover the screen. I have tried this case, but the opening at the top got so loose it would end up falling out. So, are there any good cases that cover the screen? Ideally I wouldn't wan't a flip case as I find they get in the way - however a book case like the one above would be great. Any suggestions? Thanks.
