AT&T Fires Up 850MHz 3G In Atlanta

I have noticed a small difference thus far in college park...My father stated his 3g at home where it was always crappy is better than his edge in douglasville ..I do know that yesterday a coworker dropped 2 calls on his att 3g phone..well see today when i drive around downtown connector and try talking during peak hrs on the interstate where i get the bulk of my drops..up to this point sprint drops fewer calls than att thats bad
