I use my company exchange email and in order to do it, my phone shall be authorized on the server. But, if I reset the phone or install new update - it always changes its so called Device ID. Any idea how to keep the same Device ID or a way manually to change it? And what is this ID?! I have a fixed UDID, serial number and IMEI. But on the top of them - I have and this Device ID.
