Research In Motion (RIM), seeking to boost the appeal of its BlackBerrys and revive slowing sales, plans to enable models expected next year to run applications built for Google Inc’s Android operating system, three people familiar with the plan said.

BlackBerrys that run on RIM’s new QNX software will be Android-compatible, said the people, who asked not to be identified because the effort isn’t public. RIM has said it plans to introduce QNX phones in “early” 2012, according to media reports. 

M is rebuilding its range of devices around QNX and is looking to add features that appeal to customers who had grown weary of the aging BlackBerry portfolio and its narrower selection of apps. There are more than 250,000 apps available from Google’s Android Market, or about six times as many as in RIM’s App World, a factor in helping Android become the world’s top smartphone platform.

“Being able to run Android apps, that’s a big plus,” said Steven Li, a Raymond James Ltd analyst in Toronto with an “outperform” rating on the stock. “If you get the tonnage of Android apps and the top 50 apps through BlackBerry’s App World, that addresses many of the concerns people have about RIM’s ecosystem.”

A handful of models that RIM introduced this month were its first new phones in a year, a gap that caused the BlackBerry to lose ground. Its share of the global smartphone market fell to 12 per cent in the second quarter from 19 per cent a year earlier, according to Gartner Inc. Over the same period, iPhone maker Apple Inc climbed to 18 per cent from 14 per cent, and Android rose to 43 per cent of the market.
