I have the same phone, and I agree, it does scratch easily, I am on my 2nd one currently.
I have not found a good case, but good luck!
The one they sell at verizon is no where near stylish.
Scroll down to *Belt Clips and Cases*
The ones i thought were nice are,
-Pink Case with Wrist Strap
-Cream Dooney and Bourke®
-Dusty Blue Dooney and Bourke®
If your phone is getting scratched very often on the screen then I recommend to stick lcd screen protective film which is freely available in the phone accessory shop.
