1. Does it matter if I do it before or after the OTA update? In other words should I deny them until I unlock or does it not matter? 2. If I decide to wait to unlock, is it a big deal to backup everything on my phone and restore it after I unlock? (I'm aware unlocking wipes the phone which is why I ask) 3. Unlocked phones still receive and can instill OTA updates automatically without problem correct? Thanks in advance!
