Here's a quick tip today to myself for the future which might be helpful to some of you as well: When I switch from one phone to another it takes ages to transfer all the calendar entries as I have well over a thousand on my Nokia Symbian OS phone. Most of them are years old and not very useful anymore. Deleting them one by one is not really an option. But I just found out that it's possible to batch delete them from a certain date backwards. Go to calendar – month view – options – delete entries – select date. It even figures out to leave the yearly recurring ones in. Very nice and smooth!
