Iphone 5 activation lock email?

Ok i have a problem. Firstly my iphone is not stolen. I had it and it was working and everything. I planned to sell it but knowingly to me about this activation lock feature i just created basically a junk apple id to sell with the iphone so i didn't have to give them my apple account on the spot. I just filled in all the stuff with garbage cuz i didn't know it would totally lock the phone like this. I sold the phone a few months ago and the person has been wanting to install apps but couldn't cuz the junk account is on there. I had to refund cuz i couldn't remember the info and password. I think if i can know which email i used to create it i can remember the password or at least put myself back into the mindset i was in. Cuz i put in random info for the security questions i won't be able to guess it to retrieve it. I believe i put in my email address as the backup account but i can't get to the forgot password without the account id and i can't get to the account id without the security questions.

Is there ANY way to find out which email address the iphone is activation locked to without the security questions or backup email address, basically without the iforgot thing?

You can connect it to the computer and mount it via iTunes, then select the phone and choose Restore Phone, it will wipe the phone clean with no account info whatsoever. You should have done that in the first place before you sold your phone.
