Simplynoise is great, and its brown noise stream is half of my solution to cubicle noise. The other half is a pair of shooting range style earmuffs. The model I use is called "Peltor Optime 105," and I find them very comfortable.
I put my earbuds in, put my earmuffs over them, and set the brown noise feed playing at a very low volume. It's kind of silly looking, but the ability to concentrate regardless of what's going on around me is well worth it.
