Patience is on its lowest limits as RIM keeps delaying the release date of its upcoming smartphone platform - dubbed BlackBerry 10. However, it looks as RIM is working on a fantastic operating system slated to debut in early 2013.

Last month, folks at N4BB came up with some alleged images of the new BlackBerry Messenger for BlackBerry 10 OS. The tech site is back again with more pictures associated with the new messenger. The latest images of the messenger showcase the user interface and keyboard layout.

The tech site hints at several hidden features in the messenger that can only be pulled up with user gestures and keyboard shortcuts, saving some precious screen real estate. As a hint, for N-series smartphone that feature a physical keyboard, shortcuts can be like C for new chat, N for next day, T for top, and S for search.

The Users Profile function in BlackBerry Messenger for BB10 is reportedly accommodating some changes. The modified navigation bar purportedly allows users to easily switch between users timeline and installed apps.

RIM appears to be still working on the design as one of the screenshots show that the onscreen keyboard for L-series BlackBerry devices is yet to be finalized.

Previous rumors suggest that BlackBerry Messenger in BB10 will include themes support allowing users to change colors of the messenger. Light themes will give best readability, while dark themes will improve battery performance by minimizing power drawn by the OLED display.

According to a previous report, RIM is working on a Siri-like voice assistant app for BlackBerry 10 OS. Rumors are rife that BBM will support voice controls. In the recent past, RIM also confirmed that BBM will support video chat.

If these surfacing images are real, we are waiting eagerly to swipe our fingers across the new BlackBerry Messenger. BlackBerry fans will simply love the new OS and its features. However, we will have to wait till the next year to see what's stowed away in RIM's secret vault.
