Yeah, Jay! You have to lead my example, haven't you heard that before
I can't really think of anything super amazing that I've done with my handset. In my opinion, the coolest thing I've done with my handset is preach Android to those who see my phone, and express interest in it. I've already persuaded two people to buy Android phones, so that is cool, right?
One time I called for an ambulance for someone who collapsed in German class, and was unconscious, but any phone could've done that in my opinion. I have used the maps feature on several occasions to un-lose myself though, as well as others.
