All those I've seen (mostly abroad where I've used wireless in restaurants, airports, etc) allow you to use fake details. I've never registered with true information to use public wireless.
That is really great for you. Here there is not such thing. Go anywhere with public wireless, a hotspot or whatever, connect to their network and try to browse around. Bing, "please choose one of our plans: per hour, day, week or month". Type in your credit card number and you are "free" to go. Of course, you can try a stolen ID and/or credit card combination, but then you are at your own risk.
