The Register reports that LG will ship the first UMA handset: UMA uses a local link to connect to a voice signal to an existing cellular infrastructure. Many analysts expect cell operators to push UMA as a way to move load from cell towers to home and office Wi-Fi (and even wired) networks. LG’s LG-CL400 handset should be the first to hit the U.S. market, Andrew Orlowski reports.
The article says that BenQ’s UMA PocketPC handset is slowly coming to market, while Nokia and Symbian will work with Kineto Wireless to produce UMA devices.
The key difference between Internet telephony using VoIP and UMA is that UMA doesn’t transit voice data over the public Internet. UMA will probably require partnerships with service providers to be entirely effective.

Just a comment on your note that UMA doesn't transport Voice over the public internet. In fact that's the whole point of UMA. You can use your corporate or home WLAN AP (that is connected to the internet) to gain access to the mobile operators services.
The traffic is tunnelled to the operators access node using IPSec tunneling and IKE authentication (usink EAP-SIM or EAP-AKA). So the voice traffic does travel on the public internet albeit tunnelled.
If you ppoint was that it doesn't provide access to other VoIP services on the public internet, that is true. But then again that is true for most current VoIP solutions that require some gateways to connect to other systems.
[Editor's note: This is, of course, true, but I would contrast UMA with something like Speakeasy Networks's VoIP deployment in which Speakeasy only offers VoIP to its DSL/digital line subscribers. They split voice at the edge rather than transiting voice beyond their local network.--gf]
