Updated iphone to 7.0.2 How to update itunes so it recognizes it?

Question

I updated my iphone to 7.0.2 but now itunes doesn't recognize it, so I need to update itunes on my Mac, but can't because it requires os x 10.6.8  Can i get this update? My mac is running 10.5.8.  This is the info on my Mac:

Why wouldn't Apple warn its consumers before letting them download an update on the iphone that can't be used with their itunes??? It's infuriating!!!!!

I believe you can get to OS X 10.6.8 on your Mac.  Here's how to purchase it:

You would have to purchase Snow Leopard, then do all its software updating to get to OS X 10.6.8.  At that point, your OS X version would be almost three years behind current (which is 10.8.5).
I disagree with your assertion that Apple does not publicize which version of iTunes is required for a specific version of iOS.
