How to get Gamecenter account back?

So about 1 or 2 years ago I left my IPod on a bus (I know… ), and I just now got an IPhone 4S. I had Dragonvale on my IPod and I was really far into the game, and now that I can play it again, I want to play on my old gamecenter account so that I have all of my progress. The only problem is I don't know what email I could've used or my password. The only thing I do know is my Nickname or whatever it's called. Is there anyway to get my info?

Added (1). Nevermind, got it.

  • How to unlink my Outlook account and my Gmail account? A while back, I linked these accounts together somehow (it's been so long I forgot how) so I would only have to access one account to read all my email, but now when I get an email in my Gmail account, I get that exact same email in my Outlook account a few minutes later, and I keep getting notification noises on my iPhone and have to spend time deleting the extra emails. It's really annoying me and I want to undo it, but I don't know how!
