Is there is a alternative for UDID. My app will not be going to App Store as i'm using enterprise distribution. So is there any replacement. I tied advertising identifier, open udid, UIID and secure UDID. But if the phone is reset then i will get a new UDID. Any help would be appreciated.
After trying all possible replacements. Advertising identifier is the best way to go. It remains same even after phone reset when i tested. If the user turn it off in the settings then we get a null value. Except for this hitch, this is the best replacement so far. Will update if i find any other better replacements.
