I woke about 3 weeks ago to a similar problem with my 3GS. When I plugged it into the charger it would just eventually get to the picture where it says to restore it from ITunes. Tried that but just shows the apple like your video. I ended up getting a 4S and the 3GS continues to show the apple while plugged into a computer. I didnt try to update the ios when it happened it was charging overnight and I woke up tp it that way.So , after all that , I dont know if yours is bricked , but I'm interested in the replies you get to your question.
