Completing an unlock process
I was going though the process of unlocking my old phone, I just got a new one. So I received an email saying my phone was unlocked and to back up my old phone before erasing it. So if I already have everything on my new phone, can I just go ahead and erase the old iPhone? I know this is probably a stupid question, but I don't want to mess up and do something wrong! Thanks for the Help!
