Don't know why it's silly. I don't think it's unreasonable for tmobile to communicate what they're doing better than they have. I would expect that orders would go out in the order they were received, and they're clearly not. At the very least, they should communicate why they're going out in a different order (geography, stock levels on certain types, random number generator, picking numbers out of a hat, whatever).
Look, I know it's just a phone, but we're all in this thread having some fun obsessing over them. Similarly, if you were in line at an amusement park, how would you feel if the park just randomly let other people in before you?
