Abstract: A method, system, and apparatus for sharing contact information between a first mobile device (e.g. user-operated mobile device) and a second mobile device (e.g., third party-operated mobile device). A plurality of contacts are loaded by an end-user onto the first mobile device through an application installed on the first mobile device. The plurality of contacts can then be accessed on the second mobile device through the application installed on the second mobile device, when authenticated by the end-user. One or more contacts from the contact list can be provided a customizable notification originating from the second mobile device. One or more contacts from the contact list can also be shared with (i.e., downloaded to) the second mobile device. When the end-user terminates a session with the application on the second mobile device, the second mobile device no longer has access to the end user's plurality of contacts on the application.
