Hi. i am wondering: can I use the Iphone as a remote controler? for instance; when i'm sitting and browsing on my Iphone, searching the web for my favorite sites, can i switch to control my radio/tv or even pc? to change the mp3, radiostation, tv channel or movie i'm watching from my harddisk? and if so, how does it work. Does it need special written software? or is the onboard bluetooth software and hardware enough?
