thanks for moving my thread!
ive visited the htc website and it shows the media link compatible devices.
which are DESIRE, ONE, ONE MAX, and ONE MINI. But on the media link support site says any htc phone running sense 4+ should work fine. Other sites say any ONE series phone is compatible.
but i will email HTC on this issues because i really want the media link and don't want to return it. but we will see.
