I got a shit $3.99 case from Amazon, silicone skin over hard case. Probably doubles the thickness of the phone.

What I did, when I bought it was start at the cheapest piece of shit they had and worked my way up reading only the negative reviews, taking into accoumt the general public is dumb as shit. Didn't take me long. First one everybody said the holes were miscut. Secomd one I saw, I bought and it will turn a year old in December.

Even if it takes you 3 cheapies to get to one you like, you can leave negative reviews of them and they might refund you to get you to take the reviews down.

Finally, if your silicome case loses its tackiness, clean the friggin thing. I use eye glass spray. Take the thing off, spritz inside and out, then wipe clean with a rag.
