BlackBerry Flip Phones
The first BlackBerry to feature a flip open design was the Pearl 8220, which was introduced in the latter part of 2008 and was first offered by cell carrier T-Mobile. This phone was the first to offer a clam-shell form factor instead of the normal bar form that most BlackBerry fans were used to. The design of this phone was intended to help those users who were upgrading to their first smartphone, offering the ability to browse the web, watch videos, listen to music, check e-mail, and more.
Besides the obvious differences between bar and flip phones, the Pearl had a sunken track pad and a bigger and raised keyboard, which differed from the regular style of a BlackBerry phone. This version of the Pearl line also featured a 2 megapixel camera, a full QWERTY keyboard, and wireless Internet support. The size of the phone, when closed, was about the same size as some of the other BlackBerry phones (such as the original Pearl or the Bold), though when the phone is opened, it has a much larger radius in terms of height.
The latest BlackBerry flip phone to hit the market is the Style 9670, which features a very nice and slick design, a 5 megapixel camera, VGA video recording, trackpad, and full QWERTY keyboard. The phone also features the new BlackBerry OS 6, allowing for even faster web browsing, connecting socially, and checking e-mail.
As with most smartphones, the Style supports apps to customize the phone to a user's personal preferences and increase the functionality, from health apps to entertainment. The height of the 9670 is 3 inches when closed, 6 inches when opened and it weighs about 4 ounces.
