First time iphone buyer here. I've done some research online, and there seems to be thousands of different cases for this phone. Could someone help me narrow the field a bit? I'm looking for a case that is: - High quality - Slim and form fitting - Provides decent impact resistance - Doesn't interfere with signal (like the element vapor apparently does) I'm not opposed to the bumper style cases because I love the way the glass back looks. But if I went with a bumper are there clear back protectors available to protect from keys/coins in pockets? I've done quite a bit of browsing of this subject on my own, but there is no worse feeling than buying something on the Internet and not turn out to be what you expected. So I would value your opinions greatly. Thanks!
