AT&T recently announced that iPhones can now get free WiFi at their hotspots, which are located at Starbucks, Barnes and Noble, etc. Apparently, you can do the same with your laptop. Just change the user agent of your browser to that of the iPhone browser.
On a side note, my N770 is still being repaired. I sent it out 4/21 and the Nokia repair center has had it for a week:
