Interesting. Any idea why AT&T can't make their hotspots around nyc not suck? I'd love to use them to save data, but I end up disabling my WiFi just to keep my phone from auto-connecting and then not functioning.
On some versions of Android it is possible to set the system up to check for the existence of a working Internet connection and then disconnect from wifi if there isn't one.
Thanks for the tip. I think this is what you're talking about
