I got an email today from AT&T saying it would now be possible to manage an iPad account online. I was happy to hear that, since currently there is no way to figure out how much data AT&T thinks you're using if you are on the grandfathered unlimited plan. So the address they give for this is http://www.att.com/ipad, but that just brings you to their main page about the iPad. Trying to register or sign in doesn't work. It says you are supposed to be able to use "the same login credentials as on the iPad." What's more, now if I try to access account information from the iPad itself, I get a message about maintenance. Has anyone gotten this to work? Am I completely missing how to do this?
