Yeah, new phones are fun toys and all, but you're upset because 1 phone is arriving 1 business day after the other one? I don't think this scenario implies anything other than ATT may not process all orders in a strict FIFO queue. It wouldn't surprise me if your order was held up because you're the secondary on the account, but this hardly seems like an issue worth expending any time or energy over. Sorry, I don't mean to be so dismissive of your question, but the world frequently operates in a slightly erratic, non-linear fashion. 99% of it isn't worth getting yourself worked up about.
