Research In Motion, the maker of the BlackBerry e-mail phone, disappointed investors with its initial forecast for the second quarter, and the stock has not recovered. The company had said it would launch its new flagship model, the Bold, in the U.S. during the quarter, but it has been delayed, and no U.S. launch date has been announced. However, analysts say RIM’s overall sales have still been strong, and the arrival of several new models later this year positions the company for a strong holiday season, even though competition in the smartphone field is intensifying.
