The news led to a 15 per cent fall in the Canadian firm's shares yesterday (Thursday, 16th), Reuters has reported.
This comes ahead of RIM's planned release of the iPhone and powerful Android smartphones.
RIM has, however, warned that the new devices might not hit US stores until late August.
"The company is going into the abyss of a transition, and even if they get a new model, it's a new model on the old platform," commented BGC Partners analyst Colin Gillis, who has been critical of the firm's recent business decisions.
Earlier this week, RIM launched the eagerly anticipated PlayBook tablet in the UK.
The new device boasts a dual-core 1GHz processor and 1GB of RAM. The PlayBook boasts Adobe Flash Player 10.1 and a clever interface.
Added to this, the handset allows users to play an HD video while surfing the web.
