Disappointed by its limitations

I bought the hands free upgrade only to find out it cant do what I want. This is the first app I would want a refund.
You cant use wired headphones on an iphone4 to listen or speak. You cant use a connected Bluetooth headset to listen or speak on a iphone4s. Connecting to wifi is easy but I saw no way to connect the 2 phones through a Bluetooth network. If you are looking for an easy motorcycle/bicycle intercom app, this is not the one! Yes, the audio was clear but honestly the program feels like it was built in a less tech savvy world! No ability to use headphones or Bluetooth headsets? Come on, what am I paying .99 cents for?
