Hey guys from modmyi, this is my first post in this site. I have a 3gs 32g, model mb717ll. I had to install firmware 3.1.3 because my phone crashed and I had to restore it.

Well the problem I have with my phone is:
it crashes after I have plugged in to my car radio, it doesn't matter what app is on, sometimes I'm just listening to music and it will crash.

Can you tell me if there is a way I can fix this, thank you.
