RIM may make BlackBerry OS open source

Research In Motion, which makes BlackBerry phones, may be looking at making the operating system open, which will allow other manufacturers to make smartphones using the platform.

“We get a lot of offers to make BlackBerry operating system open for other manufacturers to manufacture phones based on this OS. But we are yet to take a call on that,” said Carlo Chiarello, senior vice president, smartphone business at RIM.
