The X Factor season 1 premiered on 04/09/2004 when Jack was 16y 5mo old so could technically have taken part as there was a 16-24 category. Probably more likely to be season 2 onwards (20/08/2005) though due to filming etc.

If we can narrow the year/age/season down that would help greatly.
Also this might be an issue:
