Dell :: Studio Internal 14z Bluetooth

Is it possible to add internal bluetooth to the 14z after the fact? If so, what is the part needed to do this? While we're at it, what about wireless N?

Backstory - Ordered my laptop early December, took delivery mid December. I'm thrilled with the product except for the fact that it doesn't have bluetooth. I thought I had chosen that option, but upon looking at my invoice it appears I didn't. I went back through the customize engine on Dell's website and interestingly enough, I don't see anywhere you can choose bluetooth. Searched their parts website with no luck. Searched Google with no luck. So I tried to email Dell customer service. 3 weeks later, they finally told me to email/call tech support. So I called tech support yesterday. They told me that the wireless and bluetooth internal options are integrated onto the motherboard and have to be specified at the time of order. The only solution she could give me was to return the laptop and re-order it. The problem I voiced with that was that there isn't any way to specify bluetooth (or wireless N for that matter) on the customize page on Dell's website. Of course, she said she couldn't help with that and I needed to go back to customer service. Obviously, I was pretty irate (no cussing though! I kept my cool, but made it obvious I was upset) and she gave me a line that CS's lines were down and I needed to call them back in an hour.

So before I call CS, I'd like to try to get some more information. If you guys can help, I'd really appreciate it. Otherwise, I'm about ready to tell them to send a call tag send this thing back simply based on how terrible their after the sale service has been.
