My phones have shipped and will be here tomorrow. Here's the timeline, and note that apparently my order was held up until both phones were avail to ship:
9/28: ordered 2 iphone6+ 128GB (silver ship by 10/24 and gray ship by 10/31)
10/24: my silver didn't ship, verizon extremely unhelpful and no email updates
10/24: found this forum, THANKS for all the help you guys!
10/27: Iconic status changed to S around 7pm
10/28: was able to get tracking number via FedEx ref lookup using ACE info
10/28: verizon finally sent me an email at 6pm with tracking info
10/28: fedex picked up the phone and it's in Memphis TN (7pm)
10/29: phone still appears to be in Memphis with scheduled delivery 10/30 by 4:30pm
I will never order a phone through verizon again, they have the worst operations team and customer service I've ever seen. I will also never order more than 1 phone per order. I didn't realize verizon would hold my silver phone that was ready to ship on 10/24 until the gray phone arrived.
Thanks again for everyone who posted useful info!
