This isn't 100% accurate. The problem lies on what address you are given, most of the time it's already a NATed IP. However, many carriers can switch you to a real 'external' IP - which is generally used for VPN because sometimes NAT can interfere with VPN (assuming you can get past the CSRs).

However, even though this would be a publicly addressable IP - I imagine that they would still put in restrictions/firewall to prevent you from doing exactly what you are trying to do. – Oct 2 '12 at 4:28 •.

In this case if you were deadset on serving something from your phone you could have a reverse SSH tunnel (or some sort of similar proxy) but this would require you to have a box that is accessible via the internet. Basically all the communication would go to that box then forwarded to your phone. I imagine it's against any carriers TOS, but if you have something that is low traffic - they probably wouldn't care.

When you want to log in remotely to the 3G router from the internet, type for example and it will prompt you for username and password for the router (if any). Port forwarding: From Forwarding » Virtual Servers, type the port and the IP for which you want to forward, and this will work.
