It seems like you wanna go around wardiving, which lemme tell you friend is not only unethical but also illegal, not only that but you also risk getting caught on honeypot wi-fi zones !
If I am not wrong, no one who is in tight and right accordance with the rules and unsaid yet understood ethics of this community, will be able to help you out. I am sorry if I sound rather harsh for someone who's hardly started posting, but I say this in the best interests of preserving and strenghtening the spirit in which this community has been founded.
Lemme add, for the one who's determined to find a way, right or wrong, if he's preserving enough, he will eventually find it ! You may eventually find someplace which offers you these, but it is only fair enough to give it a thought or two if it is really worth it !
I hope you are letting them know and maybe even helping them pay their internet bill...there's 3 unsecured wireless networks I could totally use in my apartments, but I'm not going to use them out of principle.
