Research In Motion has begun showing its new BlackBerry OS smartphones to wireless carriers around the world, although it will take months before start selling it.

The future of struggling RIM depends on the success of smartphones running the new BlackBerry 10 operating system. The much-delayed system is due out early next year.

Andrew McLeod, managing director of RIM's Canadian operations, said Thursday that feedback from wireless carriers has been positive. McLeod said the company will begin to discuss the product launches and other business aspects with the carriers soon.

Alec Saunders, vice president of developer relations for RIM, said RIM is still "months and months" away from shipping the devices. RIM hosted hundreds of app developers at a conference near the company's headquarters on Thursday. Saunders has been trying to rally software developers to build for the new BlackBerry platform.

The new BlackBerrys will be released months after Apple is expected to launch the iPhone 5.
