RIM shares rebound after drop last week

Research In Motion stock bounced back Thursday from some of the heavy losses it suffered last week when the issue got hammered after the BlackBerry maker disclosed a change in the fee structure for services used with its smartphone devices. On the Toronto Stock Exchange, RIM shares jumped $1.20 or 11.43 per cent to close at $11.70. The stock had plunged about 25 per cent last week as analysts raised concerns about less revenue from the lucrative service fees charged by the company to use its secure network.
