Sense getting my BlackBerry tour a few weeks ago, I have been dealing with keeping my address book, google contacts, and my phone all in sync with each other. Well what I didn’t realize is that in Snow Leopard, the included this feature! Inside of Address Book, head to Preferences, and then accounts, and click the box that says sync with Google! This way I am now able to sync my computer address book with Google and my Tour via the Blackberry Desktop Manager!

you can take it a step further and use Google Sync on your BlackBerry to sync with your Google contacts and calendar. That way you don’t have to manually sync with your computer all the time. I’ve been using GooSync for a long time and it’s a really great OTA sync app.
