NEW YORK ( TheStreet) -- Research In Motion ( RIMM) shares climbed 7.13% to $16.97 before market open on Tuesday, after CEO Thorsten Heins told German newspaper Die Welt that he may license the BlackBerry OS to other manufacturers.

Heins has "not ruled out" licensing the forthcoming operating system to the company's rivals, according to a translation of the interview obtained by TechCrunch.

RIM will unveil its BlackBerry 10 technology on Jan. 30.
