I lost my iphone and didn't have the app to find it?

I went to a party a couple nights ago and completely blacked out, I have no recollection of where my phone is or what happened to it and it hasn't show up yet and I'm a little worried. The last thing I remember is being outside with my phone in the road then nothing. I don't have any of the apps that help you find your iphone but I'm wondering if there's any alternative ways to locate it. I did have a gps app on my iphone but I don't know if that would help at all. Any suggestions?

Added (1). If it wasn't dead how would I use the gps app to find it?

If it's dead, you're out of luck finding it by the gps app. Maybe the cops can track it but I'd doubt they do anything.

You can't do any thing… Did you try callin it?

If you have an ipod, or you know anyone else who has an iphone download the "find my iphone app"

You put in your apple id and password (the one you use to buy apps/music/etc)
and it will locate it for you, if that doesn't work someone already reset the whole phone so i'm sorry.
Hopefully you have insurance
