Just to add a bit more on this, this feature is referred to as UMA, which is in tests with the T-Mobile market in select areas (I think Seattle right now mainly); not only does it require a handset with WiFi, the handset must also know how to handle a UMA handoff to a wireless access point - which is also UMA enabled. Right now 2 devices are being tested with a custom WiFi router that I hear is a D-Link w/custom T-Mobile firmware.

The point here is multifold:
- having just WiFi is not enough, tons of phones have WiFi. You *can* use VOIP client(s) that will work that way, put it's not a true handoff like the UMA technology.
- the carrier has to support this (access point, handset, service enablement, etc.) and as far as I can tell, only T-Mobile is working on it. Basically this is a loss-leader for any carrier, as it gives a user "free minutes" on their WiFi link so to speak. Hence T-Mo charging $20 for the service (going on marketing here, I don't live in Seattle so haven't tried any of this).
Of course this is all about voice service; it would be really interesting if UMA handled the BlackBerry data services somehow in the same fashion, but I can't even begin to guess how they'd do it...
