0 BlackBerry Bold 9900

We won't dwell too much on the design portion of this review, but suffice it to say that the BlackBerry Bold 9900 mirrors the build quality of the BlackBerry Bold 9930. It's a marriage of high-quality plastic and stainless steel curves that results in a sleek and svelte premium handset. It's just as wide as the original BlackBerry Bold, which results in a larger display and roomier keyboard, and the 2.8-inch display is sharper and more vibrant than before. You can read more about its design in our review of the Bold 9930.

Features
The Bold 9900 ships with BlackBerry OS 7, which doesn't look very different from OS 6, but does carry a lot of improvements under the hood. These include a new Liquid Graphics technology that the company says improves graphics and the responsiveness of the touch screen, a speedier Web browser with HTML 5 video support, augmented-reality apps, 720p HD video, voice-activated universal search, and NFC support. You can read more about OS 7 in our review of the BlackBerry Torch 9810.

Many of the Bold 9900's features are the same as the 9930's, so we'll focus on a few software differences in this review. T-Mobile has preinstalled a few apps on the Bold 9900, like the T-Mobile Mall and its own Web2go Web browser. We didn't notice too many differences between the T-Mobile browser and the default BlackBerry one--both loaded pages quickly and efficiently. There are a few menu option differences, but they're essentially the same.
