In early September, we noted that workers were in Tompkins Square Park doing whatever it is you do to install WiFi equipment... And according to Patrick Hedlund at DNAinfo, the free wireless service went live yesterday.
What you need to know, per DNA:
Users can connect to the "attwifi" network by selecting the network and then clicking a box agreeing to the company’s terms and conditions. No usernames or passwords are needed, and there are no limits on use.
Anyway, just in time for Occupy Tompkins Square Park Saturday...
