open it up and give it a few days to dry. If you can find some of that silicate stuff they use in packaging to draw any moisture out it may survive if you place it in a box with a sachet or 2. Whether or not the spin cycle and bashing it about has caused any physical damage remains to be seen. But for it to reboot means it still switches on so all is not lost yet

You could claim on insurance if you have accidental damage or you could take out a phone policy wait a month or 2 then " lose" it lol( not that I in any way advocate fraud in this manner )
