In Android, there’s an advanced settings application called “Testing” which can be launched by entering *#*#4636#*#* (*#*#INFO#*#*) into the phone application’s dialer. I then attempted to bookmark a tel: URI of the number but found out that the browser application does not allow tel: URIs as bookmarks, claiming they are invalid. I have made a simple Android webapp that redirects all subsequent visits after the first visit to this application, and gave it a fancy launcher icon from the Tango Icon Library. The QR Code in this post points to the webapp.
