I can think of a couple ways for you to get your desired effect.
1. If you only want to have the phone and email show up on one of the panels you can use margins to slide down the icons to the bottom.
Like this.
Note: I only made this to show you what I had in mind but you could probably with some effort make a very convincing IPhone theme for UL.
2. If you want to appear for every tab you may want to consider using another launcher on your today screen positioned below UL so UL doesnt affect it. You could then set up the 2 or 4 or how ever many buttons you wanted and they would be static.
