Research in Motion shares are trading higher this morning.  

They are now trading above 10-dollars, which comes on the heels of a 4-and-a-half per cent rally yesterday.  

RIM shares have not been this high since late June.

The reason for the jump: Jefferies & Company, which says “wireless carriers have a much more positive view of the BlackBerry 10 operating system and smartphones” than they had expected.
