I have found out some new information about why my Wrangler is taking so long to arrive. First, I must give a huge thank-you to everyone over at JK-Forum. Not only did they help me out with figuring out what the hold-up is, but they posted DaimlerChrysler's 800 number to check your order status and a list of status codes and their definitions.
It turns out that my 2007 Jeep Wrangler Unlimited with half doors isn't scheduled to go into production until February 28. That means 2 more days until I can call and check to see if there is any progress on my Jeep. It seems that they started taking orders for the half-door option on January 18th, but won't actually start building them until this Wednesday. Since I ordered mine on the first day that DC was accepting orders for the half-door option, it should (hopefully) be built this week.
The quiz from my previous post is still open to anyone who thinks they can figure out what is wrong in the picture form the 2007 Jeep Wrangler brochure (another hint: it's in the center of the picture).
