Hi,
Do you mean the top text about the ip address? or the bottom black area becoming a bit tall and swallowing something? or is it occurring above the logo? Sorry, I don't have an iphone and the emulator is showing everything is ok.
You can try this to see if the background will override using a media query, just change the file name to the new iphone background and put the code below into custom.css
@media only screen and (min-width: 480px) and (max-width: 767px) {
html.html_boxed,body{background-image:url(https://www.virtualprivateinternet.com/wp-content/uploads/2011/12/vpi_bg_test_larger.png)}html,body{background-position:top left}html,body{background-repeat:repeat}html,body{background-attachment:scroll}
}
If you want to target iphone, you can substitute the line below for the first line in the above example
@media only screen and (max-device-width: 480px) {
Here is a reference page with a bunch of media queries for various devices http://css-tricks.com/snippets/css/media-queries-for-standard-devices/
Thanks,
