Hey , it's me again, I have an idea, perhaps it could work?
I looked online and I found this website that has instructions on how to do "firmware patches" for the Samsung SGH-E900 , which is somewhat similar, from around the same time , and they used to modify the firmware directly with the "theme" that they wanted , and I guess it would be possible to do the same for the U700 as well?
I've looked everywhere for the U700AMGE1 version , can't find it to download it anywhere anymore, I've looked for phones that have it directly , on ebay , facebook, everywhere , no luck whatsoever.
Here is the site where they explain how they used to do it by themselves back in the day :
