From watching numerous preorders and releases in the past there in my humble opinion no order is given when a preorder is made and when the phone actually ships ....... I know , I know it suuucks ???
Someone preordering today will probably get his or her phone as early as someone who preordered the first half hour the preorders started ?!?!
Go to previous threads for releases for the Note 7, S6 Edges , HTC M7s and M8s which I preordered you'd see folks flipping out at someone getting a tracking number after preordering the day before and those preordering the first day not having any tracking number ......it's insaaaane in the membraaane !!!!
