Blocking app for ipod?

[coproxamol]

Have asked on CHAT, but thought I'd try here too.
I need something to download onto an ipod touch that blocks access to sites using words such as porn, sex, hot babes etc. Any ideas?

you can do that in settings / general /restrictions then choose your comfort level.

this is the how to, so pretty easy to do.

we banned the internet connection to my dd 's itouches, we tried to be fair but once rule was broken we took it off, downside is I have to do all downloads BUT i know its only the stuff I am happy with.
