Has anyone else been told by their network of the "shortage" of Jet Black variant phones, and specifically the Plus? From what I can understand all the networks are just waiting on more stock to arrive at their doorstep with no forewarning from Apple as to when this will be. I've been promised an update within 21 days, others within 7. Does anyone have any information on how the Apple supply system works? i.e, will the next 'batch' likely satisfy all orders? Is there a reason (other than "unprecidented demand) why the Plus specifically has faced delays? When will the next batch arrive with retailers, could it be over the weekend?
