Research in Motion, the maker of the Blackberry, is going through the toughest period in its history.

Its share price has slumped to a nine-year low as the company flounders against competition from rival smartphones - a far cry from the days when business executives and their Blackberries were inseparable.

It has already warned investors to expect another grim quarter.

Some fear a turnaround plan may come too late.
