I’ve been looking for a way to sync my Google calendar (that I share with my wife) and my Notes calendar (that I use for work) and have on my Blackberry. The manage imported calendars feature in Notes 8 worked well for a while but required me to manually request an ICS file from Google, download it, and import it into Notes anytime there were updates.
Yesterday I came across a tool from Google called Sync for Mobile.

This application will sync my Google calendar entries with my Blackberry calendar. Since my Blackberry calendar is connected to my Notes calendar, the entries also appear there. The best part is that I don’t have to remember manually import updates, it just does it for me. I’m not sure if there are any drawbacks since I’ve only been using it for a couple days. But so far so good.
