I'm looking for an adapter that has a Micro USB male to Apple 30 pin female with the ability to transfer audio. A few of my friends have radios that only have 30 pin connectors and I want to just carry around an adapter so when they want to hear music I have I can just whip out the adapter. I'm sorry if this is the wrong thread, this is my first post. FYI: I have an HTC EVO 4G LTE if that makes a difference.
