A San Francisco-bound United Airlines flight was forced to divert to Dallas as a precautionary measure Monday after an unclaimed BlackBerry and backpack were found on the plane. Not an unreasonable cause for alarm, if you ask us -- after all, who's ever heard of an unclaimed BlackBerry? This, of course, isn't the first time a gadget has caused security concerns. Just last month, an iPod in a toilet turned out to be the source of a bomb scare at Ottawa airport
. As with that instance, the mysterious BlackBerry turned out to be harmless and the flight eventually made its way to SF as planned. The exact BlackBerry model wasn't disclosed, though it seems safe to assume it wasn't a Pearl
-- no one would dare let one of 'em out of their sight.
