Looking at pre-ordering the X once pre-orders go up and given this is my first Apple iOS device I had a question regarding carrier logo upon boot-up. Could someone tell me if when powering on the phone if it will have the carrier logo upon starting? Also I'm wanting to do a carrier unlock from AT&T where they send you a code to unlock your device, would this be successful and streamlined as with an Android device? And last thing if the phone was unlocked by carrier if there was the carrier logo at boot-up will this remove it? Sorry if these questions come off as a bit odd but I've always purchased my devices outright and its always been unlocked versions direct from the manufacturer so I was curious as to how things would be with the new X or any iOS / iPhone for that matter.
