I setup a pre-paid data plan with AT&T for my iPad2 using Settings, cellular. And, when I look at my account info under settings, I'm assigned a phone number (I guess it's a unique identifier). I've never had an account with AT&T before.
So, I figured I'd install the myAT&T app to check on my usage (I can also do so from settings, but I'm trying different things out w/ my new iPad2). But, the id and password I use to access my AT&T account under settings doesn't work.
I also tried registering with AT&T online -- as a cellular account using the phone number assigned to my iPad account -- and this doesn't work either.
Has anyone else, who is using an iPad for the 1st time and doesn't have a previous AT&T account been able to use myAT&T or setup an online account?
