I have two iPhone 6 Plus phones with a Will Call hold placed on them. Both of them just arrived at my local UPS facility less than 20 minutes ago. So far, the tracking just says "Arrived" - not out for delivery and not confirmed held. I suspect over the next hour or so, I'll see if they complete the will call hold on them or not. Either way, the center doesn't open until 9am so it's a waiting game for me!
