I've looked for answers on this, but nobody seems to have a solution for the problem I'm having. Normally this problem is just annoying, but tonight it's made my phone near unusable. To make things short, here's my problem. I use my Eris in my car a lot to listen to last.fm and podcasts, etc. I have an auxiliary cable that goes directly into the headphone slot to my head unit in my car. When I plug it in, it shows the headphones logo and everything's fine. But for no reason at all, it will switch to the headset logo, as if there is a microphone. It will then start randomly dialing the last person I've talked to on the phone nonstop. I'll keep ending the call and going back to last.fm and it will keep dialing that person's phone number over and over again. I'm really fed up with this, and tonight it even kept doing it after I rebooted the phone when I got out of the car. I believe it's the voice dialer, and I'm wondering is there anyway I can turn this off because it's absolutely terrible and is ruining this phone for me. Thanks.
