I'm fussy about good protection which limits me with some of the pretty designs out there. So I try to find tough cases that come in nice colours.
I love the creamy white rear of the silver X, so I've chosen cases that have a clear back. I'm switching between 2 cases at the moment. One is the Caudabe Lucid Clear (in metallic silver) which is really minimalist, but has some gorgeous silver accents that complement the phone.
The other is the Spigen Crystal Shell (in rose crystal) which is more rugged but I think looks quite feminine.
I've posted lots of pics in the case megathread, but here are some front and back shots of both.
