Apologies for the late reply, but T-Mobile's US GPRS network hands out
RFC1918 space as well.
Ah, that depends on if you're on WAP, T-Mobile Internet or T-Mobile VPN.

The VPN service is exactly the same as the Internet one, except that it gives you non-NAT'd address space for VPN compatibility. (APN internet3.voicestream.com, everything else is the same). Note that you have to be provisioned on each APN now, you can't jump around like you used to be able to.

It is often stated that these are primarily cable-based providers.
In my experience many cellular providers (at least in the US) do this as
well. A GPRS connection to Cingular, even from a laptop device, will get
a 1918 address. I don't mind since my phone runs linux with no root
password (thanks motorola).
