"If you can tolerate the volatility, it's a good idea to begin dipping back in to the stock market, in solid companies with strong cash balances, little debt and great prospects," says wireless sector expert Nikhil Hutheesing.

In The Forbes Wireless Stock Watch, the advisor asks, ""In the long run, smart investments today will lead to profits down the road. One of those companies, that I now think looks attractive, is the Canadian maker of the BlackBerry - Research in Motion (NASDAQ: RIMM)."

"The Canadian company introduced the BlackBerry in 1999 and it quickly became a must-have way for employees oflarge companies to communicate through email and voice wirelessly. In its fiscal 2008 (which ended in February) the company sold nearly 14 million devices (more than double the year before).

"Recently, though, the financial crisis has dealt a strong blow to the company. Investors doubt whether RIMM can repeat the 90% growth in revenues that it achieved in fiscal 2008.

"Not only is the slowing economy a threat to growth but so is increased competition. Apple's iPhone, for example, has been a hit among consumers and now the company is pushing into the corporate market, trying to erode Research In Motion's market share.
