According to this article from PC World, it should work with the iPhone. I hope this device isn't PC only, and will work with a Mac.
 
I wish AT&T would just create a VoIP app for the iPhone which would let us migrate to WiFi seamlessly. T-Mobile sells phones that are hardware capable of VoIP over WiFi, and they offer the service for a nominal monthly fee. Surely something similar could be implemented through software on the iPhone? I'd pay to have a voice connection at work.
 
I saw this article this morning.

This is the part that concerns me:

AT&T, T-Mobile and the Federal Communications Commission had no immediate comment on whether they believe the device is legal, but said they were looking into the issue.

We'll have to wait and see if it ever reaches the light of day.
