He's asking why AT&T can't do the same thing Sprint was doing, as 
they've disconnected Sprint and are using AT&T alone.

My answer: no reason they can't, beyond not wanting to or being really 
dumb about it. Tell them you want them to advertise your netblock for 
you because you don't need BGP. You don't have to; they can easily do 
the routing and announcement for you. If they don't get it easily... 
well, I'd go back to Sprint, because you'll probably have severe 
problems later when someone updates something, breaks it and you're down 
for a week before you can get through to anyone who will listen to your 
unsupported (to them) setup. I was in the same situation years ago with 
an Eschelon/ATG circuit: they simply didn't get how to work BGP with a 
multihomed customer. I could convince them to fix it each time, but then 
it'd break 4 months later. After the 4th time they screwed up, I dumped 
them and gladly paid more for anyone else so it would actually work.
