Nokia 6136 GSM/VoWiFi phone

On the subject of GSM/VoWiFi convergence, Nokia have just announced a UMA phone in a traditional form-factor:

"The Nokia 6136, launched at the 3GSM World Congress in Barcelona, is a UMA phone that Nokia claims will be able to roam seamlessly between GSM mobile and Wi-Fi networks.

Customers will be able to use the 6136 to make VoIP calls at Wi-Fi hot spots, allowing them to avoid paying a mobile call charge — although they may have to pay for Wi-Fi access instead."
