Is it possible to stop notifications of an OTA update?

I rooted and modded my Samsung Prevail (Gingerbread) a couple weeks ago, and all is going well there.

However, I am now getting notices about an OTA system update, which I have no intention of installing. I will wait for the makers of my mod to produce a parallel version.

In the meantime, is there any way to kill the constant notices about the update?
