Griffin Tuneflex, Tuneflex AUX, or Tunflex Smartclick?

[smeg36]

I just got my iPhone 3Gs. I have the original Griffin Tuneflex for the ipod video. It fits the 3Gs pretty well, and almost everything works as it should with a couple exceptions. Of course, it get the airplane mode pop up every time I dock it. It also lowers the volume of calls while using a BT headset. I have to undock it, raise the volume with the headset, then redock. So I'm trying to figure out if the Tuneflex AUX or Smartclick fix these problems.

From what I've read, the AUX still has the problem with the airplane mode pop up. That doesn't bother me too much. It's a little annoying, but I can live with it if the AUX fits properly, and doesn't have the BT bug. Does anyone have the Smartclick, and can verify it eliminates the airplane mode pop up? Anyone using it with a BT headset that can comment on how that works? I want to be sure it's what I need before spending that much money. Thanks.
