Has anyone run into issues connecting their iPad via hotspot tethering on the iPhone? I'm using the Verizon iPhone, and when I tether my iPad to access the internet, for some reason the connection drops when it goes into sleep mode. I'm not sure if this is normal behavior for the iPad, yet it doesn't happen when it's connected to a normal wifi source (like my router at home). There it stays connected sleep mode or not. It's annoying because every time I slap my smart cover back on, the connection with the iPhone breaks, until I open the cover again.
