While waiting for a Caribbean cruise liner to set sail from the Port of Miami last November, a Chicago native with an AT&T wireless card and Slingbox decided to catch the Bears vs. Lions football game on his laptop. The end result? A $28,067.31 bill from for international data charges, despite the ship never leaving the harbor. Apparently the card was picking up a signal it shouldn't have, and while the bill was eventually dropped to $290.65 after a considerable number of calls to customer service, let that be a warning to mobile users traveling on the fringe of international roaming areas -- and in case you were wondering, the Bears ended up winning 27 to 23.[Via
