This iPhone is currently linked to an Apple ID?

Hi there,
I am completely restoring my iPhone and I got the following error message:
"This iPhone is currently linked to an Apple ID". I have no idea what the apple ID is though that it is asking for.
Do you think the Apple Store will be able to help me and bypass this?
Thanks!

Apple ID's is used for syncing, downloading apps, Itunes and apple games. I think you should log off or delete that account.
