How to get contacts from icloud that were deleted?

I recently got the iPhone 5, and all of my contacts were backed up on iCloud. My sister got my old iPhone 4, and she deleted all of my old contacts off of the 4. That phone was still connected to iCloud, and deleted all of the contacts on my 5 as well. Needless to say, I'm gunna need to get those back. And would like to save a trip to the apple store. Ideas?
