Can't check wireless.att.com account on iPhone Mobile Safari

How can AT&T – with its 5 year exclusive on the iPhone – have a website that does not work with iPhone’s Safari?

Seriously.

I had called AT&T for something else and they mentioned my balance, which was $100+ more than usual. We were on the road, so I was going to check our usage on Mike’s iPhone. Except I couldn’t log in!

You attempt to login, it redirects somewhere, then kicks you back to the login screen.

Calling *MIN# is the official way to check your minutes. Nice, you can’t just have low-balance email alerts like all my bank accounts do? I wish Apple were its own virtual network already.
