Research In Motion unveiled the BlackBerry Z10 and Q10 devices at an event in New York hosted by RIM CEO Thorsten Heins.
The Q10 will have a physical keyboard, while the Z10 has only a touch-screen keyboard.
RIM has changed its name to BlackBerry and is banking on its BlackBerry 10 devices to make a comeback.
The BlackBerry Q10 is the first BB 10 smartphone with a QWERTY keyboard. It features a 3.1-inch display.
RIM redesigned the system to embrace the multimedia, apps and touch-screen experience prevalent today.
BlackBerry says that there are customers who are still demanding QWERTY smartphones.
BlackBerry 10 introduces ScreenShare, a brand new feature that will enable users to navigate through each others' screens and share files, images, documents and so on in real-time.
The BlackBerry Z10 sports a 4.2-inch screen with a pixel density of 355ppi offering crisp images and text. It comes with a 1.5GHz dual-core processor with 2GB RAM.
As a full-touch device, the Z10 will allow users to experience comfortable typing in both portrait and landscape mode.
In terms of design, the BlackBerry Z10 has rounded corners and a smooth overall finish with the BB logo imprinted on the back panel.
One of the new software upgrades comes in the form of an all-new BlackBerry Messenger or BBM that now features video-calling integration, in addition to the earlier text messaging.
The Z10 comes with an 8-megapixel rear camera and a 2-megapixel front camera that promises great stills and a decent video calling experience.
BlackBerry Remember is another new software feature that will allow device users to stay organised with files, tasks and notes. It also brings Evernote Integration.
BlackBerry has recently rechristened the App World to BlackBerry World and will offer music, videos and apps.
BlackBerry has roped in Alicia Keys as the new Global Creative Director for the company.
