Accidentely deleted all my contacts on my iPhone 4?

I was trying to delete an email account on my iphone and somehow accidentely deleted all of my contacts. I didn't even know you could do that.
I'm overseas right now, and don't have access to my computer. Is there any way to get them back on my phone? I have supposedly been "syncing" my contacts with iCloud but I don't see any way to get them back. I didn't have the backup button turned on.

If I can't get them while I'm away from my computer, can you please explain how I can do it once I'm home?
