I actually called T-Mobile and asked if becoming a JUMP! customer would bump ne up in line despite having ordered at about 8am CST. The rep said yes, so I got JUMP! without modifying my order and I'm hoping that I get it on launch day. Fortunately I was planning to get JUMP! anyway since the handset protection is included, which I believe is normally $8.
I'm pretty sure the "Backordered" notice on all our phones is more or less a glitch, and I'm thinking it might be fixed after this Sunday when they finish prioritizing JUMP! customers.
I had a friend who ordered a 5S last year, and it said backordered, but he received it right on time.
Sure, it's annoying that the system is saying that, but I think it might be inaccurate.

In all honesty, I know T-Mobile has botched this quite a bit, but shouldn't you be looking at the overall service of the carrier and how it meets your needs over the quality of service on a one time event that is so overbearing on servers that almost nobody was able to handle it very well?
If its so severely critical that you receive the phone on time (which I'm not sure why it is when you could get literally any other phone immediately if you /really/ needed one), then why wouldn't you have tried to use Apple's website? If it wasn't urgent enough to deal with Apple who guarantees dates, then I'm not sure what the big deal is considering how popular this phone is.
We all want our phones but I think a lot of people need to step back. They are phones, not lifesaving transplants that we need immediately.
