"The status of the talks remains unclear.
But the fact that the discussions took place, even informally, underscores the severity of the challenges facing RIM and the opportunity it presents to rivals," the publication said.
RIM has been grappling with tough times, especially dismal quarterly financial performance due to service outages in October. In recent weeks, investors have sought bold steps including management rejig to revive the fortunes of the Canadian entity.
According to the report, Co-Chief Executives Jim Balsillie and Mike Lazaridis last week acknowledged investor anger and said they would explore a wide range of operational shifts.
"So far, no bids have emerged, and Balsillie has indicated he wants to wait until the launch of RIM's new BlackBerry next year before deciding whether to engage seriously with potential buyers," the daily said quoting people familiar with the matter.
As per the daily, senior executives from all three companies frequently meet to discuss ways to enhance their partnerships and talk about their industry.
