There are too many models to list here, because RIM, the maker of BlackBerry, makes varying versions for competing wireless carriers, and these may have different features, even if they look the same. However, here?s a quick breakdown of the main flavors.
How BlackBerry Models Differ

The Bold is the top-of-the-line BlackBerry, relatively large and costly, with a wide keyboard and a big, vivid screen. The Curve is its little brother ? still sporting a good, full, keyboard, but lower-priced, smaller and lighter. The newest Curve, called the 8900, has a beautiful screen and is even sleeker than its predecessor.
The Pearl is a slimmer, low-priced, more fashion-oriented model with a truncated keyboard that has two letters on each key and relies on software to guess which one you meant to hit. The Pearl Flip is much like the Pearl, except, as its name implies, it?s a flip phone.
The Storm is the BlackBerry line?s most direct competitor to the Apple iPhone. It?s the only BlackBerry without a physical keyboard, instead relying on a large, beautiful touch screen for typing and navigation. Unlike on the iPhone, however, the Storm provides physical feedback each time you press down on the screen.
