I'm getting ready to purchase my first iPhone next week and I'm looking at cases that don't cover the bezel (like this case), though I will have a screen shield on the phone. (I want minimal bulk.) How scratchable is the bezel? Will it be jacked up and nasty-looking in no time if I have case that doesn't cover the silver bezel? I'm pretty careful with my electronics though it will be in and out of my purse and pocket.
