Interesting... I'm on 4.2.190 (Orange UK) and I certainly don't have that option.
HOWEVER... that made me think. My old phone (blackberry 8100) was on 4.2.194 and I've just had a look, and it indeed has the "Keep appointments" option and it is set to 60 days. Somehow the setting must have moved across when I migrated phones (I used the migrate feature in blackberry desktop).
So I suppose my options are to leave it as it is, or try to find an upgrade, or wipe everything and re-sync. Unless someone knows a way of tweaking that setting which clearly exists, just not in the UI.
