In my car my iPhone 4 worked fine but when I plug the 4S in and play audio through my car stereo I hear a high-frequency noise that's not there with the 4. I remember this issue long ago on the 3GS and it was fixed with a software update so hopefully this will be too. Anyone else experience this?
Got a tip for us?

Assuming you are plugged to the charging on your phone it is feed back from your power plug getting into the audio wire. A software update can not always fix that.
I have seen it across multiple chargers and it happens to and it relative to the engine speed.
Yes. I have the high frequency noise when I'm charging my 4S in the car and listening to my jams.
Yeah I made a topic on this too, last week.
When I connect it via an auxiliary cable I can hear a high frequency pitch sound, like a whistle. Really, really, really, really annoying, because I listen so much in my car.
Google this issue and it's all over Apple community forums too.
I think everyone will have it but haven't realised yet.
Only issue I have with my iPhone.
