The best way to do this is to listen for netlink route announcements.
That way it's completely instantaneous and without polling. Look here
for an example using python-netlink:

http://git.freesmartphone.org/?p=framework.git;a=blob;f=tools/dump-netlink

Note that if you're on FSO I expect that after full integration of
connman (milestone6), we will have a global signal like

org.freesmartphone.Network.ConnectionStatus( s:means, b:online )

'means' being a string that indicates the type, like "GPRS/ppp",
"IP/usb0", "IP/bnep0", etc.

that you can use.
