The iPhone is incredible, but one thing that is keeping me from buying one is lack of any kind of internet filtering to keep out porn and other bad stuff. I've got filters on all my computers, and would love one for the iPhone as well. So far I have contacted two filtering companies (Intego and Covenant Eyes), and neither has anything for the iPhone. I'm told AT&T offers some optional filtering on the Edge network (via the Parental Controls which you access by logging into their website), but I have no idea how good it is, and the AT&T sales rep told me you can't edit or customize it, i.e. you can't block a specific site for example. Has anyone heard if there are any such 3rd party apps in development? Thanks.
