Today after i updated my iPhone, i plugged in the USB in my car and played music and started to hear this crackling noise. Thought my speakers were blown, but the noise wasn't there when i played CDs. Then i hear other friends of mine have been getting this crackling noise after updating to 4.1, even on an iPod Touch. Anyone else having this issue?? What a major F up by apple, now i can't listen to music anymore.
