In the past the three weeks between a beta usually meant that they were getting to a point where the kinks were not as numerous and therefore there was just less to have to fix and give developers to test out. With iOS 7 I feel like the three weeks could be an indication of lots of work being done between b3 and b4. I was under the assumption that the developer site being down was probably a big reason we didn't see an update, but with maverick updating that chance got slimmer. I know that developers need the Xcode but I still think apple could have released without the site. Quick reply...I'm talking to you. Any thoughts?
