It's a joy to see that due to the flexibility and openness of Android, pretty much all major Android based smartphones sold by Orange UK now come with UMA Wi-Fi installed. A recent post on Recombu says, Orange is shipping the Samsung Galaxy S II, LG phones, Huawei phones, HTC phones, etc. etc with UMA. Not only does UMA extend in-house coverage of voice and SMS services in places where neither GSM nor UMTS is available by tunneling the connection of the smartphone and the Mobile Switching Center over Wi-fi, but it also shows how easy voice over LTE could be achieved in the future. After all, like Wi-Fi, LTE is an end-to-end IP based technology. Perhaps I'm repeating myself, but the thought just keeps coming back. For the details see here.
