Multiple internet network connections.

Hello everybody,
I have just got a new laptop with Windows 7 (finally!) My question is this:
Is there a way to configure multiple internet connections with either a preferred primary connection or a way that I can manually route applications to a specific internet connection.
For example I am connect to a corporate lan for corporate email, unix access etc, can I plug in my 3g card and then use that connection when i use msn or a specific browser? I want both connections active at the same time, but the banned stuff on the corporate network to use my 3g connection.

Many,many thanx in advance!

There is a way to choose between home and public networks, how many choices that you have may depend upon your version of Windows 7. There are five versions. I'm in the middle of the pack with Home Premium 64 Bit. If you have Pro or Ultimate there may be more choices. There is also Starter and Home Basic. Which do you have?
