http://www.verizonwireless.com/b2c/splash/splash.jsp?v=9 Is anyone using this service already? Is the billing completely flat $79.99 for unlimited use? We signed up for this service 4 weeks ago. Been using it all day long for mobile internet access non stop, day after day. Just dawned on us if this is really unlimited for 79.99 or there is a hidden clause? Just want to know if we need to leave the country before we get the bill. Anyone using it?
