missing images in iPhone using Titanium

Note to future self: If you build an app in Titanium -- do NOT create a folder in the images directory called 'iphone' to place iphone specific images there. They will show up in the emulator but not on the device. I ran into this a few months ago but didn't document the solution and just spent another 2 hours trying to debug it a separate time. Use any other name than 'iphone'!!!
