iRiver is launching a touch-screen Wi-Fi VOIP, media and internet device dubbed iRiver Wave in Korea.
The Wi-Fi enabled media player supports voice calls and SMS via Wi-Fi hotspots. A music service called Bugs music lets iRiver Wave users download music directly onto the device.
KT provides the network services for the iRiver Wave, which is comparable to the Nokia Tablets.
Features of the iRiver Wave include 3 inch WGVGA resolution touch-screen, 4GB memory, MP3, WMA and Ogg file format support and USB.
Measurements of the iRiver Wave are 110.5x52.5x15.5mm.

We will most likely not be seeing the iRiver Wave outside of Korea.
