The two new handsets are essentially the same but the Bold 9900 supports High Speed Packet Access(HSPA)+ connectivity, while the Bold 9930 is an international device supporting CDMA and GSM networks.
The new Bolds and the BlackBerry 7 OS will be launched this summer, but unfortunately the current devices won't be upgradeable to the new OS due to hardware restrictions according to RIM. This is a major drawback since all the Blackberrys purchased recently will become outdated.
Here is a video of the Blackberry handsets, courtesy Crackberry.
The BlackBerry devices run on Qualcomm's 1.2GHz Snapdragon processor; have 768MB of RAM and 8GB of internal storage which can be extended up to 32GB with a MicroSD card. The mobiles have a 5 mega pixel camera with Flash which can also record High Definition videos at 720p, a feature absent in earlier models of BlackBerry.
They have a 2.8 inch capacitive touchscreen featuring RIM's Liquid Graphics technology and a pixel density of 287 dpi, track pads and full QWERTY keypads and are the thinnest BlackBerry smartphones till date at a mere 10.5mm width. They come with a brushed stainless-steel surround and a high-gloss glass-weave back plate. The inclusion of touch screens means you can use both the track pad and the screen for the functioning of the device.
