Porns blocked on GSM GPRS and Edge
You have to go through the same gatekeeper... Although I have to giggle each time I read a post on a network operators forum threatening to leave because of the kiddy filter. Iirc only three turn it off by default and then only on pay monthly; but they're never the operator the outraged customer is threatening to move to.
That said the article is wrong on one point - the solution isn't kiddy filters on 2.4Ghz; the solution is to get the government out of the censorship business and for parents to take responsibility (and they complain that todays yoof is irresponsible...)
