OTTAWA (AFP) - BlackBerry users in North America experienced outages in key functions Wednesday, Research In Motion (RIM) confirmed after similar problems were reported this week throughout the rest of the world. The glitches that impaired messaging, emails and Internet browsing in Europe, the Middle East and Africa on Monday had spread to India and South America on Tuesday and now to Canada and the United States. "BlackBerry subscribers in the Americas may be experiencing intermittent service delays this morning," said the Canada-based company that makes the smartphone.
