There's also an emerging BlueTooth issue with the iPhone 4 - suprised this hasn't been picked up more. I know from my own personal experience (I've owned every iPhone, this is the only one wiht issues) and the growing complaints: http://www.google.com/search?q=iphone+4+bluetooth+issue&...
1) The compass points about 90 degrees the wrong way
2) When I plug my phone into my car's auxiliary input and use the phone to make calls, it broadcasts my voice over the speakers, as if it were a microphone. My iPhone 3G didn't do this.
Anybody else have these issues?
