C-motech separable wireless router

The wireless router has been around for years, but C-motech decided to reinvent the proverbial wheel by introducing the separable wireless router in Korea. Simply known as the Bridge (CMR-100S), this device allows several users to connect to it simultaneously, where each user can connect to the Internet via WCDMA or WiBro, essentially covering the whole of South Korea using but a single device. Perhaps in a country with varying networks available, a device like the Bridge would come in handy, but how about modifying it for Stateside use where it works on GSM and CDMA?
