Thanks for the tips and support folks, it's really helpful!
climbnjump: The doc cleared me for using my fingers like I normally would. He said any damage that would have occurred from my exposure has already been done, things will just be sensitive for a while.
Orionengnr: The only medication I took was aspirin to open up my blood vessels so the blood could work it's way back into my fingers as much as possible. So far, time (and perhaps the Father..) has been the biggest healer and I am sure it will continue to be that way. I did sustain frostbite injuries with my left-hand, but they were only 1st and 2nd degree so I was still able to grip my phone as a camera. HOWEVER, the touch-screen couldn't detect them (frostbite makes your skin very waxy and dead...mostly because it's dead..) so I had to tap the screen with my nose to take most of those pictures. And yes, I am pretty young I suppose (Up until last July I couldn't buy my own ammo.........).
Kernel: I will certainly look into the DuoDerm product. This is the first time I've heard of it but it sounds like a great thing!
Al Thompson: I've been carrying my pocketknife (no firearms allowed on campus at GATech...yet.) on my left side, and it feels perfectly normal now. In fact, using my right hand to do most daily tasks still feels a little weird. Next time I get to the range, I'll try going full-lefty and see how it goes (dang, I should've bought the 4th gen after all!)
I think I'm going to try a better pair of gloves, probably leather. The ones that I tried are a little loose-fitting and my thumb slides around in them when I try and hit a release.
