Incorrect. The app shown on the left side of the lockscreen is your weather slot. On your homescreen this icon appears on the top right side. On the lockscreen it shows on the bottom left. This way even if you have the phone locked you can still take a quick glance at the weather conditions, temp, etc depending on what weather app you are using.
The voicemail tab can be customized to open whatever application you like. Yes, it will always say voicemail, but this was our choice to list this as most phones will have visual voicemail coming if not already.
Both of the above are explained in our original post of this thread along with the pictures, links, etc.
