In February of 2008, RIM announced that a big update was coming out for its BlackBerry handsets: OS v4.5. You can read all about the new features here and here. It ended up taking about 8 months before the update actually became available, but it's finally arrived... well, for some BlackBerries, on some wireless carriers. Rather than go nuts trying to figure out if yours is one of them, RIM has a Web site that will easily check your 'Berry and update it if applicable. Here's what you do:

1. Hop on a Windows computer running Internet Explorer 5.5 or higher.

2. Plug in your BlackBerry via USB cable.

3. Use Internet Explorer to navigate to

4.Click "Check for Updates."
