Struggling cellphone maker Nokia has found a software bug in its new flagship Lumia 900 model, dealing a blow to its ambitions to re-enter the lucrative U.S. smartphone market. The glitch, which Nokia said April 11, 2012, it would fix early next week, can in some cases cause the phone to lose its data connection. REUTERS/Rick Wilking/Files
