Communication system with server for identification information retrieval and related methods

摘要

A communication system may include a mobile wireless communications device, and a server having an email source interface module configured to communicate with an email source, and a proxy module cooperating with the email source interface module. The proxy module may be configured to communicate with the mobile wireless communications device using a first communications protocol and a second different communications protocol, authenticate the mobile wireless communications device by at least retrieving identification information therefrom using an initial display screen based upon the first communications protocol, and transmit a selectable settings interface to the mobile wireless communications device for accessing the email source and being based upon the second different communications protocol.
