as of 8:25am (ET) Out For Delivery (6s 64/SG) ...probably sometime after 2 or 3 pm, as that's the usual time for UPS here. I just happened to be scheduled off today, I think that makes it harder to be patient.
This is the second time I've pre-ordered, last time was iPhone 5, after having 3g for over 3 years, then a used 3gs for 6 months, I couldn't wait, ordered from Apple just after midnight (3am ET). Last year I waited until October, switched from AT&T (had them since Cingular days - 2004) and had a hard time getting a 64GB 6 in space gray, went with 128GB went that finally came in. The reason for pre-ordering this time is mostly because of issues (network issues, I think) with the iPhone 6 and to get LTE band 12, as I may get more chance of better indoor reception. I'm also hoping what I read about bluetooth 4.1 & 4.2 is true, they are supposed to have less interference with the other radios over older BT. So, for me, it's more about function than the new features...those are just added benefits. I also decided to get on the JOD lease/free upgrade plan for now. I can go without applecare, and upgrade yearly, b4 the warranty runs out, and get new LTE bands, if they become available (and, got a military grade drop-tested case and screen protector - OWC's Nuguard KXs, which is a bit big for me, but less bulky than an otterbox). While T-Mobile has definitely improved over the last year, AT&T still had better reception and data...the addition of LTE band 12, and their continual building out may help this for T-Mobile, and keep me long-term.
FYI: I want to say again, for those that haven't JOD'd or ordered a new phone yet, find a T-Mo store and go there, this works much better than anything over the phone. Anything over the phone (billing, customer service, whatever) is the one thing T-Mo needs to work on the most.
