"Great phone with STATIC and RINGING-MAJOR HARDWARE FLAW"1.0 starson by Kevin_Camp
Cons: If you plan on connecting your phone into your car through the headphone jack you will experience static and a high pitch ring loud.
Summary: When I replaced my phone the second time with Apple it was still producing static and a ringing sound in the car. The guy I talked to at Car Toys said this was a major flaw with only the iPhone 4s (not iPhone 4, iPhone 3gs etc.) and that they are getting in around a person a day complaining about this problem. They confirmed that it was NOT a speaker, cable or stereo problem that the Genius Bar guy thought it would be. This issue only occurs in cars and potentially portable speakers since this is a grounding issue (home speakers will be fine). I am an Apple Fanboy and am not trying to hate on their quality products, but this was a pretty big deal to me.
