I prefer the June cycle, but only because I like to stand in line for my phone. We will be moving to Boston here in September, so unless they end up releasing in the summer, I will probably just pre-order online and have it shipped to me. No waiting outside in the cold.

I don't know that there would have been a difference in fixing the antenna issue had they waited until October to release the iPhone 4. I am not even really all that sure that the 4S went through any more QA than did the 4. I suspect the October date had more to do with supply. Apple had a whole lot more units ready for the 4S launch than they did previous years.
