[Plugin: List Related Attachments] Unable to view links on an iPhone

Have been happily using this plugin to list about 40 attachments on a page of our website, discovered today that the list does not display on an iPhone (tried on two separate phones). Might also be related to the WP Touch plugin?

In the meantime I am also asking a friend to check how it looks on an iPad.
