Adding Jarrad to CC so that he can test your patch as well.

Jarrad, if you could provide your Tested-by: to Alan's patch, I'd 
appreciate it (that would mean that we've reached the right super-position 
of both the patches you guys submitted).

I don't own the device, so I fully depend on what you guys submit and 
test.

Thanks.
