If you're not on UP, the device will ship by 3/14 and arrive 3/16. You won't receive a device on the 18th, which is a Sunday.
Strange. I preordered on 3/2. I had an email and a text this morning that my phone shipped. The email says the expected delivery date is 3/16 but FedEx tracking shows scheduled delivery for this Wed. 3/14. Hope it's Wednesday, lol.
