CL2G0 is not another application to manage your personal contact list. CL2G0 is for business environment. It maintains updated list of contacts for formal dynamic community, group, committee, etc. This page describes only mobile client part of the project. To function, it requires back end database and infrastructure established to manage list membership, contact details and access permissions. The mobile client only presents centralized and managed contact information on your device. Currently CL2G0 supports iPhone (iPod Touch, iPad) and Blackberry platforms (with slight difference in implementation due to specific update technologies). CL2G0 is capable of keeping contact list information on the device (so it is available even when there is no connection to any network) , receive regular updates over Data network or Wi-Fi, and provide a number of convenience features such as contacts search, support for multiple lists, and information retrieval from a lost device etc.
