One of the original BlackBerry's best features was its full QWERTY keyboard, which made writing emails and text messages a very simple affair. But the downside of that keyboard was that it made the handset big and bulky, resulting in most BlackBerry users carrying a separate mobile phone for making voice calls. Research In Motion (RIM) tried to address this issue with the BlackBerry 7100 with varying degrees of success. But now RIM has released a new handset aimed at the user who wants to carry one device for email and phone, the BlackBerry 7130g.
