T41 Black PDair Leather Case for Samsung Galaxy S WiFi 4.2 / Galaxy Player 4.2 YP-GI1 (Wireless Phone Accessory)
A little expensive for a hull mp3 but that's the only one I have found to samsung. It's for my 10 year old daughter, so it is a bit austere. But with a few stickers, it becomes more fun. It seems tough, we'll see over time.
