Well, I just got up and running on GM 4.0. I have to say that after all the nice updates and features, one of the most basic (and often most asked for) is missing. What I really need is a 'locked' home screen that allows me to show information from my Calendar, etc. I can't tell you how many birthdays, and other important dates I've missed by not knowing about them, and the alternative is to check the Calendar every single day, but this gets redundant and is an extra task that doesn't need to happen is iOS had a proper Home screen. Seriously... I need to email Steve about this.
