I restarted my phone today and now a dot shows up that remains. It does fade with time. I touch it and it opens to several options: siri, device, favorites and home. I have 601 running. I just wonder if one of the favorites can be set to turn wireless on/off. Sorry if this is a foolish question but I looked through the operators manual and don't see it. It's hard because I don't know what it's called.
