I've never heard of PTSN.
I did find 2 spcsdns.net addresses, I am assuming those are sprints dns servers.
Nevermind, I tried that on wifi and it showed my IP resolved. Not sure why 3g gives 3 different addresses.
I used an app called Network Info II. If you press the IP in the top right, it will populate your IP and dns addresses.
I have found a bunch of root apps that will change dns servers, so it must be possible.
