I thought I figured out this issue but was wrong. In my car I have bluetooth called Uconnect which works fine. The problem is that I connect my mogul to a aux jack (cable) in to phone for MP3's. The bluetooth Ucoonect will place or receive the call but as soon as it does it hangs up. Now I figured that this problem was becase uconnect and cable plug wbere fighting out because they are both Hands Free devices. Now with the new ROM from sprint it worked fine. I found this out while listening to MP3's and the phone rang and connected to the uconnect and I was talking on the phone with the calbe plugged in. But since the New ROM is such a mess I had to go back to the old Sprint rom and the problem is back. So now I think its a bluetooth issue? Any help would be greatful from you guys.
