This is still a VERY emerging technology. Hopefully it will eventually work but there are a lot of moving parts. Its main dependence is on the ability of the networks to seamlessly transfer the data stream from one protocol to another without any interruption to the end user. The WLAN part would effectively be running on a wi-fi network which means it's a TCP/IP data stream. So you have to convert from that to whatever GSM is etc. Now think about trying to do that while you're driving down the highway at 80 miles an hour. It's a cool concept but still has a long way to go.
In my opinion, that will be huge for the viability of the one-device concept. High speed voice and data in one device with widely accessable access points. . . cool
