Did you call in and complain because you saw a posting about the issue and decided to try it on your phone? Would you have even noticed had the news not broken about the issue? Was it because you were consistently getting more dropped calls than you had before and you noticed this issue on your own?
I suspect most of the complaints are the former (no I am not trying to say that applies specifically to your complaint, just asking the question.) There are many posts and some actual scientific analysis that shows the antenna performance is actually better than the previous models which corresponds to my experience with the two iPhone 4's that I have in my possession. There is also a lot of hyperbole around the issue that makes it very difficult to determine the severity.
