My first phone (week 27 build) had it. It was a real mess. Two days ago Applecare set up a replacement phone at the local Apple store. They did not want to do the exchange, but they did. My new phone is also a week 27 build. When I synced it, I did it as an old phone, not new, so that should not have changed anything. I have over two hours of talking with NO ISSUES. It is the phone we all want, and some were lucky enough to get right out of the box. This is admittedly a study of one, (although 'some' other people have said their replacements solved the issue). In my mind this has to be a simple QC issue. Is it a bad batch of components? Imprecise manufacturing tolerences? I'll leave that up to the people who are paid to solve the problem. Good quality control is paramount.
