exactly the same here.

next time, try hard resetting and wait (plug the phone to you computer). if nothing happens hardreset again. wait. try hard reset again and wait.
if any of those times itunes sees the phone dont hard reset again. fyi: the pineapple is still there, even if itunes sees the phone. but in my case when itunes sees the phone it's on it's way back...
(sorry i'm in a hurry, i hope you understand my instructions)

waiting period: up to 15 min each time.

for me, that usually brings it back.
