What date did you submit? I submitted 3/9 and date is still pending.
I'm in the same boat. AT&T, submitted on 3/8, shipping date of 4/1. I have not received any tracking info. I was hoping it would just show up, but it sounds like everyone is getting the shipping email now.
People have reported in this thread that they have received their shipment confirmation with tracking numbers after the delivery of their Gear VR.
