Otterbox says it shipping the 4S on 10/14.. so I doubt they got an advanced 4S(knowing Apples security control) so its obvious they just redesigned the current iphone 4 cases and just packed into a more profitable price tag.. Thats OK, but dont lie and tell me a 4S wont fit into a regular iphone 4 case
Otter box cases with 4S printed on them surfaced 2 weeks before the announcement. I'd say they knew.
