This is honestly the first phone I've had where I feel like I NEED a case on it. Not because the build quality is bad and might get damaged, but because it looks so damn good and I would be crushed to see a dent or scratch on it. I looked at the T-Mobile silicon case and it seems pretty good, but the question is, does it stick to the inside of your pocket? If it does, I may just pick up a TPU case online somewhere.
