Posted: Updated:

WATERLOO, Ont. - Research In Motion (TSX:RIM) shares traded at a seven-month high on Tuesday, surging almost six per cent after the BlackBerry maker said it has released the 'gold' build of its developer toolkit.

The build, the company says, contains all the final elements developers need to create apps from the coming BlackBerry 10 operating system.

The Waterloo, Ont.-based company also said developer interest in BlackBerry 10 is growing ahead of it being unveiled on Jan. 30.

RIM says top application developers have already committed to building apps for the new system.

RIM shares closed up 68 cents, or 5.79 per cent, to $12.42 on the Toronto Stock Exchange on Tuesday. The stock hasn't traded in that territory since early May.

BlackBerry 10 is widely considered a make or break product launch for Research in Motion.
