Hey - I see in the FAQ that they say AT&T Wifi will be "available to attendees at Coachella". Does anyone know how it works? Is it free? Do you have to have a cell plan with them to use it? Is there a per session or day charge? Coming from Canada and curious as to how it will work. Last couple of years texting to friends to try and meet up has been brutal....some texts show up hours later, and with wifi we can use iPod touch "Messages" app for free.
