Up to now, the Vodafone software for OSX has included PowerPC code ie not Universal Binary. This is an Activity Monitor snapshot
Step forward v3.04.06.00, which is now Universal, and even has a re-worked interface.
Download it from here
install and launch. It replaces the Vodafone folder, and all the PowerPC bits. But, this version does not work with 10.6 Snow Leopard.
It sports a new tabbed interface. The first tab shows the status of your network connections
and the fourth tells you what devices are connected
I have just one complaint, other than the lack of Snow Leopard compatability..
Its uses a LOT of CPU, a real CPU hog!
Update: new version, Snow Leopard compatible, from the above link v3.04.07.00
