I'm not getting any of the new connectivity controls / reverse connect etc... Would I be right assuming it's because I'm running Airfoil v3.5.7 on my powerbook G4? If so, are there any plans to get v.3 to be compatible with this or is the only way to have to update to OS 10.6 and get v.4?

If this is the case, you might want to highlight it on the itunes app store just for clarity.

Don't get me wrong - it looks awesome and it seems to have all the improvements I've been waiting for speakers touch to include, I'm just gutted I can't seem to get it to work!
