Your mobile what?

So, I've aquired a new, small, metal/plastic/electronic thingy. I broke down and finally got a cell phone. It's pretty cool, and I think that I've figured out all the things that it does, but I'm sure that it'll surprise me with some things. This is really the first time that I've had a real mobile phone - aside from a TracPhone that was a piece of crap. If anything, it'll help me keep in touch with people whom I haven't heard from in a while.
