Just found out my son is going on Tublr.com! If you don't already know about this app, it's terrible. Filled with teen pictures, bad language and just an over all bad place for kids to go.

I need something that will block or filter this site on iPod Touch's, Mac's and Window PC's as well as cell phone. Is there some kind of hardware router or firewall device that will allow me to control what my son see's on the internet? I know there is software that works with browsers but these are applications that the kids load onto what ever device they are using. Facebook also has an application that loads onto the iPod's.

Any help would be appreciated.

Thanks..
