If it hadn’t been leaked so damn much, the BlackBerry Pearl Flip 8220 would be something of a surprise. Not simply because it’s the first-ever clamshell BlackBerry, but the fact that RIM went in this direction at all, especially when you look at the rest of its new phones, with their clean, almost aerodynamic lines, and compare them to this beefy slab of a phone. Landing on T-Mobile today, the big-boned Pearl Flip is aimed at people graduating to their first smartphone, and it definitely has its own kind of charm.
