Abstract: A device, system and method for providing an exclusive wireless data transfer service between one or more authorized mobile applications (apps) and one or more remote servers through an in-vehicle telematics device is shown and described. The invention includes establishing a wireless network connection between the WWAN communications electronics of the vehicle telematics device and one or more remote servers and a wireless network connection between the WPAN communications electronics of the vehicle telematics device and a mobile device hosting one or more authorized apps. The invention further includes using specialized application programming interfaces (APIs) that exclusively grant certain authorized apps the ability to use the two wireless network connections to transfer data back and forth between the remote server and apps on the mobile device while prohibiting all other apps and services from doing the same.
