PinePhone BE & Pinebook Pro shipping update thread

[PineNewbie]

I received the email that my PinePhone BE shipped two days ago (4/20), however, as of today (4/22) the tracking says
"Unknown" This number can't be found at this moment. It's not available in the carrier's system yet. Please check back later.

It also says the carrier is USPS not DHL like others have noted. A friend of mine ordered the same phone on the same day as I did, got the email that it had shipped on the same day as I did, lives not far from me. The friend's carrier was DHL and delivery is expected today (amazingly fast, so that's cool). 

Any insight about mine still showing as "unknown" in the system would be appreciated.

Update 4/23: ..the tracking link in my email went to www.17track.net which was the wrong shipper. They sent me a link to where is should have gone track.4px.com/ and my shipment is there and it currently says "Depart from facility to service provider". Great communication from the Pine crew...thank you! What I am curious about now is...why my friend's phone was sent via DHL and mine is going USPS. There is no option to choose carriers when you check out at purchase. My friend got the phone in 2 days and mine will probably take  much much longer. Not a big deal, just a curiosity.
