Does not work with iPhone

Have tried and tried to get this thing to work on my iPhone 4S but just wont link to my iPhones Bluetooth. It worked a couple of times after plugging in and out, turn phone off, rebooting phone, now I get nothing at all. I contacted New Potato support and all they could tell me is what I had already done. DO NOT BUY!!! DOES NOT WORK WITH IPHONES. Waisted my hard earned $$$

End of my rope about TuneLink, v1.2.0
