It’s always a surprise to find that one of the top selling items on the ShopCrackBerry.com accessory site is the replacement BlackBerry trackball.

Its been up there at the top since it first went on sale, without dropping a single notch. That may well change though between the touchscreen and the introduction of the touch sensitive trackpad. This shouldn’t come as a surprise though when it happens as there are literally millions of BlackBerry Curves, Pearls and 8800 smartphones in use out there.

From time to time these trackballs do wear out and need to be replaced, have you ever had to replace your trackball on your BlackBerry, do you carry a spare? I would recommend carrying a spare especially if you are travelling. Have a look at the video to see how to change your trackball yourself. Source – crackberry.com
