Canadian mobile phone maker Research In Motion is hard at work with the development of new BlackBerry smartphones, and a series of new details on the company's plans for the future have just emerged into the wild via a series of videos. Three of the company's unannounced BlackBerry smartphones can be seen in the videos below, including the BlackBerry 9300, BlackBerry 9670 and BlackBerry 9800.

All three handsets have been spotted into the wild before, and some of you should be familiar with them in a certain manner. However, there are still a wide range of details on the three mobile phones that haven't been brought to light until now, and some of them were unveiled in the available videos, which were published online by the guys over at salomondrin.net (via BGR).

Among the pieces of info available now on the three BlackBerry mobile phones, we can count the fact that the BlackBerry 9300, which is also known under the name of Kepler, is expected to arrive on the airwaves of T-Mobile in purple. It seems that the 9300 is set to become the next BlackBerry Curve, and that it would sport 3G and Wi-Fi connectivity options.

The BlackBerry 9670 and BlackBerry 9800 come to the market with BlackBerry OS 6 on board, though they sport different form factors. The former is expected to come to the market as a flip device, while the latter should sport a sliding design.

BlackBerry 9670 clamshell spotted in the second video below is an older model, which sports a 3.2 photo snapper, but the handset should arrive on shelves with a 5-megapixel camera. Other known specs on this handset include 512MB ROM and 4GB of internal memory. As for the BlackBerry 9800 slider that can be seen in the third video below, it should arrive on AT&T's airwaves, while sporting a touchscreen display, similar with that on the BlackBerry Storm.
