When you're reserving a phone on iUP, does Apple "reserve" the phone while you're placing the order? Say, you chose the SG X 256GB, and it shows you the locations it is available, you pick a location, click Continue and fill in your details. In the meantime, is the phone reserved by Apple? Like, by the time you finalise the process and click the Reserve button, you wont lose your place, right? It's not like you click the Reserve button and it throws an error saying "the phone is no longer available" or something, right?
