So on a Storm or a Tour (curve is similar), actually any newer BlackBerry, it is quite a simple little process. Let me break it down,
1. Go into your email settings and add your Gmail account. On a Blackberry that has never had an email or doesn't currently have an email attached to it your defaults for calender and messages will be setup automatically. If not you must go into options->advanced options->defaults and then change to your Gmail account.
2. Go to m.google.com/sync and download Google sync.
3. Open Google sync and click your BlackBerry menu button
(looks like this
and click options. From this menu enable calender sync, contact sync, and reminder sync if you wish.
4. Now run sync!!! You will notice that you can now edit contacts on your PC as well as merge, edit, and delete entries. The system knows where you made a change to your account (device or computer). So you will never loose anything, unless of course you want to loose something or someone...
Watch this video from Google where they explain it in Google terms.
I have been using sync for a month or two now and I love it. When I worked for Verizon I would even help customers install it on their BlackBerry. Check it out, no more wires, it's the future...
