Here's how I transferred all my Blackberry Torch 9800's calendar items (1245 of them) to my new Samsung Galaxy S4
1. Download iCalendar Lite from
Free software downloads and software reviews - CNET Download.com
2. Create new (local) calendar, and save as 'yourcal.ics'
3. Open Blackberry Desktop Software (update software, and backup all device data)
4. Click 'Organizer' button
5. Click 'Calendar' box, then 'Configure'
6. Sync Direction: One way to you computer only; Sync: All calendar entries
7. Calendar account: Windows Calendar; configure.... locate 'yourcal.ics'
8. Click 'Sync Organizer' at lower right of BDS window
9. If you don't already have an @hotmail.com address, I suggest you create one for the transfer purpose. You can remove the account later on - it's only to facilitate the transfer. I haven't tried doing this with a Google account, but if it ain't broke, don't fix.
10. Once in Hotmail.com, go to Calendar and click on 'Import' at top of screen
11. Choose new or existing calendar, locate 'yourcal.ics' and import calendar.
Hope this works for you as well as it worked for me!
