I don't think sonic has asymmetric internet anywhere. It used to be symmetric gig, now they're deploying symmetric 10gig. And the price is $49, although they just announced an increase to $59.

I had symmetric 10Gb for over a year, until they sent a new modem. When I tested the speed again, it was asymmetric. I figure it's the new modem, but the change may have been made before. I don't usually upload >1Gb, so I didn't notice when it actually happened.
