FreeMyApps install a mobileconfig file on iOS device to register this device, and get this device's info(especially UDID).
Then download and install a recommended app on this device in FreeMyApps, credits added.
I guess when the downloaded app opened, device's info had also been sended to FreeMyApps' server. But app can't get device's UDID, what did the app send to server? How do the server decide whether this app-installed device is the same device which registered with a mobileconfig?
And suggest is grateful! Best regards
