While I am more of a fan of their Nseries devices, the announcement nevertheless caught my eye since the 6300i includes WLAN for browsing and VoIP.

This is mainly designed for very rural areas and I am not quite sure what kind of terminal is required at this distance to communicate with the cell tower.
