How do I know if I have iTunes 10.5.1

[Rain Drop]

I have 3.2.2 on my iPad. There are more things every day I can't do. I've never upgraded because I don't own a p.c. So finally, I've decided to upgrade on someone else's computer. I read it's imperative I have iTunes 10.5.1. I'm told all my apps are up to date. Does that mean I already have it?

It means the version of iTunes on the PC.
