Hi guys, So yesterday, my family has upgraded our wireless plan to At&t's new "UNLIMITED CHOICE" plan. We now finally have unlimited data. I know there is a hotspot option for $20/m. And I am dying to get rid this crappy At&t DSL, which cost $30+/m. So you get the idea. But I don't want a hotspot device that uses only battery. Is there any hotspot device that can plug-in to a regular power socket? Another thing is stopping me to do this is my mom's email, once cancel the DSL service, what will happen to her email address. Of course, that's another matter to discuss with At&t later.
