I believe you're confusing "routable" with "public".  The 10.x.x.x is a 
private class A network, and most (all?) wireless providers use private 
networks with a distant gateway that routes traffic once the IP's are 
resolved.  Nameservers can be on a private network and resolve public 
names.  Any IP address is routable if it's used in proper context.  
Protocols like NetBIOS are not (unless it's encapsulated within TCP/IP).

I use AT&T, and I signed up for a media package that includes unlimited 
data with 200 text messages.  That add on plan is around $20/mo, but any 
limited data plan would cost me thousands as I would always go over the 
limit, and then it's 5 cents per K.... when I'm using around 90M(?) 
(bill says 90,836 (KB/MB) ???) of data, I would be in serious trouble.

When I connect, my ppp0 IP address is 10.x.x.x with nameservers on the 
172.x.x.x private subnet, and my gprs works perfectly, however I've had 
problems with the SHR connect/disconnect python script, so I made my own 
based on the wiki.  (love being able to download TangoGPS map tiles when 
I'm on the road. :) )
