Messages Customiser allows you to change the background image, among other things.
Installed Message Customiser, located images using ifile and replaced with my desired image.
Make sure you use an image size of 744x1392.. You also need 2 of the same image, one portrait and one landscape. I figured out Message Customiser uses this file size "only" as it's background on the 5,5c and 5s. All other iPhone's use a smaller resolution image as default within the app...
Hope that helps....

Oh, don't forget to rename your image exactly the same as the default image file. You'll also have to delete the original image file before renaming, won't let you have 2 of the same image files at the same time and in the same location.
