I posted a quick iPhone 5 homescreen earlier after I installed my first and current theme.
After messing with source code, photoshop, and old user mod widgets I used on my iPhone 4, I came up with a light and dark version of Auros...
Since my first post, I added recessed shadowing around the icons, time/date and weather widgets, and changed stock icons that didn't make sense to me.
Credits: henftling, pinoy, the_durben, dnate, schnedi, chevymusclecar, Max_Pa1n... and others I missed that helped me create my current homescreens.
Could you possibly upload those or send me a link to download your theme? That's the best one I've seen in this thread.
