Connect to other networks while using a 3G modem

A lot of 3G (or EDGE) external modems (USB or ExpressCard) require special software to build up a connection. My two modems from different providers use GlobeTrotter Connect and E-plus Online Connect (the latter a re-branding by my provider). As I understand it, these applications set up new network interfaces and group them in a new location setting. All existing network interfaces get disabled when a connection is established and the system is switched to this location.

This may be obvious, but it took me a while before I tried it out. One can simply re-add other network interface (i.e. Wifi or Ethernet) to these locations, and then be connected to both the internet via the 3G modem, and to local networks at the same time (eg, for streaming to an Airport Express).
