User blog comment:Filheinz/Clarifications regarding the Icon Event/@comment-7621385-20130504184040

1: It can take up to 48 hours (2 days) for the icon to be unlocked once you get 10 wins. It's just the icon you picked without the orange clock.

2: Yes. Unless you actually CHANGE the icon, the wins will be retained.

3: Like mentioned in the 1st answer, it's the original icon you picked without the orange clock. You keep that one, and the icon WITH the orange clock will still remain until the event is over.

Last: Not quite understanding your last question, you went back in time. o.O
