Thanks... and info for AT&T wifi users
Thanks, Joe for the info. I am getting a better understanding of Wifi now. For all you AT&T users - below is a link on the AT&T site that helps you find "hotspots" in your area. There are basic hotspots (for example, many McDonald's resturuants) which are free - I believe at those, your phone will automatically log you into the network. Then there are premier hotspots (such as some Barnes and Noble's) where you pay a small fee for usage (varies with location). I haven't tried to log onto a premier hotspot yet, so I don't know all the details. Then I think there are hotspots for other wireless networks (such as Verizon, and T-Mobile and at places such as Starbucks.) I think you have to have a plan with these providers to get on the network at their hotspots.
The bottom line is that Wifi is sparcely available for now... Anyway, for AT&T customers - here is the link to the site where you can search for your local "hotspots":
