BB Storm :: Recovering Auto-deleted Appointments?

I have a new Storm and have just suffered a major disaster due to the default setting that deletes old appointments in Calendar if they are over 60 days old.

Blackberry - change your defaults to retain any information FOREVER rather than hiding a default deep in the Calendar options set to 60 days which no-one knows about till it is too late - I have lost 4 years of critical project schedules and activities simply because I bought a new phone!! Judging by a couple of other posts on these forums others have also suffered this unwanted 60-day default. It is just so much more logical that the Users make a concious decision to have automatic deletion.

how I can recover my lost calendar entries - since they have been deleted out of my Outlook as well.
