As someone else posted, dialpad.cab will do it.
Go to
http://benhirashima.com/software/
download dialpad.cab.
copy it to your phone.
run it on your phone.
then restart your phone.
It works... and it's free! (thanks to the author.)
PS. - I know this post is "late", but I just got a Q and was trying to solve the same problem, so I posted my results in case it helps someone else.

P.P.S. - I have the Q9H from ATT, and it works fine.
