First, the work you've done is awesome on the mobile applications. Excellent!
I did notice that when I added the images, there was a gap between the top (global) image and the bottom (startpage) image. I did a search to find if you posted a solution in the forums but didn't find anything. But I did find a solution online that might help if someone mentions this.
I have the 3rd gen iPad and it came up as this: I found the issue in your imagevue.mobile.css here:
Code
.heading img, .welcome img { width: 100%; }
Code
.heading img, .welcome img { width: 100%; display: block;}
Code
.heading>a, .welcome>a { display: block; line-height: 0; }
.heading>div, .welcome>div {margin: 15px;}
