for my video Ipod I use an IOgear bluetooth transmiter, this one :

I have an ipod case that has rubber at the top so it is secure and allows streaming to my bluetooth headphones (use these a lot a work).
Now since Apple decided to do the recessed_so_nothing_in_the_world_will_fit_in_it plug on the iphone this is not really an option. Yes I can get the long skinny adapter and add this but that's way to geek even for me. Rumor has it that Apple accidentally add streaming in 1.1.1 release , can anyone confirm that ?
