I received the shipping information mail last Friday but posti.fi has not received the parcel yet.
Hopefully Jolla has stopped all further shipments until the bug has been tracked down and fixed. I guess this will save a lot of costs and goodwill.
Since the first C2s are on their way back to Jolla, Jolla should soon be able to analyzing the failing phones. I would not be surprised if unintended switching on during shipment and some random attempt to connect to wifi network might be a problem (since so many C2s arrived in a switched-on state)
