Sorry if this is a stupid question. My wife just picked up a rezound. I currently have a Galaxy Nexus and an OD before that. I've never seen this option before and I'm guessing it's an HTC sense thing. In any case, she claims that she keeps losing connection and is blaming it on the wi-fi at home. I noticed the option for Mobile Network, I turned it off and started browsing some webpages with no issues. Can someone explain what it does? The manual has no info and I can't find any online.
