Yongnuo/T3i help

Hi first post. I was hoping someone could help me out. I have a canon t3i and I mistakenly bought the Nikon version of this flash- "YONGNUO YN-468 II TTL Flash Speedlite for Nikon". I'm so new I didn't even realize the shoe communication is different between nikon and canon. I can't return the flash, so I was hoping there's a way I can still use it with my t3i on-camera.
The reason I got this flash was because of the auto ettl feature, bummer... Do they make a low-cost adapter that will retain the auto function? Or should I just chalk this one up and buy the correct canon version? Would a pc connection work?
Thanks for any advice on a solution.

Interested in the answer. I thought the shoe connections on Canon and Nikon were the same and only Sony was the odd ball.

No, yes, no.

Canon and Nikon use completely different TTL algorithms and hotshoes. You won't be able to use this flash with your camera's TTL function at all I'm afraid.

The Yongnuo does have a slave mode, though, so you will be able to use your T3i's built-in flash to trigger the flash to fire remotely, but you will be stuck with manual power settings. You might also be able to use the flash in manual mode on the camera's hotshoe - I think Canon and Nikon trigger flashes in the same way (the central pin on the hotshoe) even though the pin layout for TTL purposes is different.

ok, thanks, I'll buy another canon version. I did try the S2 slave mode off the camera's flash, very cool. I'll still find use for this one for sure.
