Today's post is not one of my own creations/discoveries, but something I have had a lot of people asking about. Siri - available only on the iPhone 4S for now - is a virtual assistant, who can respond to voice commands to do a large number of functions for you. But she can't do everything. So, what kinds of things can she do? What kinds of things will she respond to? CydiaHelp.Com has compiled a useful list of which I excerpt only a tiny portion below.
Requesting remindersThe search capabilities of Google, Yelp, and Wolfram Alpha are the biggest wildcards. This is a window in a whole world of information. For instance, if you say "I have a flat tire", then Siri will look up towing services in the area. Or if you ask "What is the capital of Uganda?" it will look that up using Wolfram Alpha. I recommend playing a bit with it, until you get comfortable with the kinds of info she has available to you.

Also, keep in mind Siri's language parsing is server-side, so Apple may be able to add new functions in between releases of iOS.
