Research In Motion (NASDAQ:RIMM) will hand out prototype BlackBerry 10 smartphone to thousands of developers at its BlackBerry Jam conference in May. The devices won't run the finalized version of the Blackberry 10 software that RIM will unveil later this year, but will instead be used by RIM to demonstrate that progress is being made in bringing the platform to market. "The experience on this device from a consumer's perspective is not in any way indicative of what the final experience on BlackBerry 10 will be like," Alec Saunders, RIM's vice president of developer relations, told Bloomberg. "We are holding that back to create the interest around that at launch time." BlackBerry 10 smartphones are considered critical to RIM's future, especially because the company does not intend to roll out a software revamp before RIM brings the new smartphones to the market sometime late this year.
