This is a device that boosts your cell signal using your broadband connection. If, like me, you have a weak, spotty or no cell connection at your home, this works great! I'm moving and will no longer need this so I'm selling. It works really, really well. http://www.att.com/standalone/3gmicrocell Asking $80 shipped (or $75 local meet/pickup). I'll deactivate it and all you need to do is go online and activate it to work with your account (instructions can be found in link above)
