My wife just got her watch and now we've been disappointed to find that it absolutely destroys her iPhone 5's wi-fi connection. I haven't seen anything about this but I can't believe we're the only ones seeing it. With both BT and w-fi on, the status bar icons both go on and off as they disconnect and reconnect. If I turn off one, the other is fine. After reading a bit, this doesn't seem surprising to me. BT and wi-fi both work on 2.4 GHz. We actually have a dual band router but the 5GHz signal just isn't reliable everywhere. A solution would be nice (besides buy a new router) but I'd just like to know someone else is seeing this!
