Have been really enjoying the Rearth Ringke Slim-Lite.
I bought a Otter Box Commuter from Amazon, it was $21 with free shipping. Case came in 4 business days.
Case offers great protection (comes with screen protector) and doesn't make the phone to big to put in your pocket.
what kind of case are you all using for your s3? i havent decided if i want something i can wear on me or something i can throw in my pocket
My vote is for the Seidio Active Case. I've had one for three different devices and the quality is always top notch. It keeps my device pocketable while giving two different textures which help it have some grip and still having protection on the back and corners. Adds just enough to the front side of the device that I can avoid adding a screen protector for any standard drops/slips I may have every now and then.
