Ah cool
Good, glad that was cleared up. With Samsung saying they has to get my phone from TMO and Samsung wouldn't be sending it and you saying what you did, really makes me think UPS is handling the processing. It is UPS planes so they can say "we will process and ship Saturday and deliver Sunday" if they wanted to do that.
If UPS is processing it or even if TMO has a warehouse next to UPS (seems they might on TX) TMO has a big contract with UPS, so I can see UPS doing things they don't normally do even for just regular business customers.
It is probably easier for UPS to do all this on Saturday, because then it isn't a sudden large level of shipping during their regular shipping days. For UPS, Saturday is probably the best time for them to do pre-orders. I don't remember who AT&T uses, but it's FedEx and UPS here basically, so they would both be doing a lot of extra work for one or two carriers and the weekend is probably best to get it all done.
