Here's the case I use currently : link deleted due to my status
It's a really stylish gel cover (black). This particular case is sold by multiple sellers on ebay, and always around the price of $2. The seller I picked mine up from had free shipping and included a screen protector! The case is great looking, easy to clean, and awesome to grip!
Here's the case I had previously, my first case used with this phone: link deleted due to my status
Another low cost and stylish case, it comes in the color white and is made out of soft silicone! I loved the white look on this dark phone, as well as the amazingly smooth finish the silicone offered. I ran into two problems that caused me to replace this though. First off it dirtied really easy from a combination of it's color and it's material. Second, a tab that held both the front and back plates together broke and which eventually caused the case to crack as well.
This isn't a holster I owned , but it's on my wishlist: link deleted due to my status
This holster looks sleek and will definitely keep my phone out of my pocket, but not too far out of reach.
