I'm trying to retrieve the UDID of a windows phone device without installing an app. Apparently you can do this for iOS devices by sending users a signed .mobileconfig file that installs a webclip that tacks on the device's UDID as a querystring parameter.
See: Read UDID from Iphone with javascript on mobile safari
I'd like to determine if something like this is possible on Windows Phone (either 7 or ideally 8). Basically e-mail a file to users that installs a live tile that links to a site that has the UDID tacked on the querystring.
