"HTC wasn't the only manufacturer showing off new Windows Mobile devices. Chi Mei also had a new Smartphone at the show. The unnamed device was a prototype smartphone with UMA technology for seamless roaming between GSM networks and personal Wi-Fi networks at home. The Chi Mei UMA phone is surprisingly small. It seems smaller than recent HTC smartphones like the SDA and 2125. Its features are pretty standard: 1.3 megapixel camera, Bluetooth, memory card slot, etc."
UMA stands for Unlicensed Mobile Access, it enables seamless delivery of mobile voice calls over Wi-Fi networks and it also enables seamless transitions between cellular and Wi-Fi networks. There is considerable speculation that T-Mobile will be launching a UMA enabled phone soon. While I am sure that it will not be this Chi Mei Smartphone, but it would be good to see a Smartphone in the UMA enabled list. ;-) I definitely like UMA based solution over Skype like VoIP applications. What are your thoughts?
