I'm not sure. I don't have a wifi-equipped router here and there are no wifi access points near enough to me to try. But I have contacted AT&T IP Support who handle their DNS servers and they have confirmed that the PTR records are missing from the IP ranges that my phone has access to. They emailed me that they have submitted a request to the team who administers the mobile ip DNS servers to add the PTR records for the affected ip blocks. They said the problem should be corrected by sometime next week. Once it is fixed (if in fact that occurs), I will test it with my phone and report back here.
