Since the direction of the air vents are correct I would leave them alone. When they installed mine I questioned many times on why my front and rears were in the opposite directions of each other. It looked very strange to me but I found out later that is how they are designed, at least for the US versions.
If any of you are purchasing ANY AT&T services could you mention that you were referred by me? My referral ID is eo4489. This would be a great help, thank you!
