EWR Wireless
I was at EWR much of this past Sunday (MR, 1/14). No, overall, it's not free. A friend told me that if you sit with your back against the wall to the main President's Club, you can pick up their (free) signal. I tried it from the Starbuck's, next door to the PC, with no luck. However, I have a B card. A G or N card might just pick it up, from there.
