AT&T is offering a new video relay app at the iPhone app store. It works with the iPhone 4 and allows deaf and hard of hearing customers to make unlimited VRS calls using the at no additional cost. AT&T has offered video relay services to customers for years, but the new AT&T VRS app provides a more convenient way for users to make VRS calls by going through Wi-Fi hotspots. The app contacts an AT&T ASL interpreter who then initiates a FaceTime video call with the user. There is also free software called AT&T Video Link that allows people to use computers to make the connection.
