So, going on the theory that a horcrux was created when Harry & Voldemort first "fought" (and it's not the scar)...I'm thinking that the "last" horcrux is something that Harry's had with him since that night, and Voldemort's battles with Harry so far is about getting the horcrux back into his control.

If this is true, then what item has Harry had with him since he was a baby and could possibly be the horcrux?
