BlackBerry (BBRY) has upped its component purchases from Taiwanese suppliers thanks to strong BB10 sales, supply chain sources tell Digitimes. The sources add Indonesian and Middle Eastern sales are healthy, and that if other emerging markets prove strong, BlackBerry is likely to ship 30M-40M smartphones in 2013 - Feb. quarter shipments totaled 6M, and were down 23% Y/Y. BBRY +1% in spite of lower NASDAQ futures. The sell-side has been arguing back and forth over BB10's early reception.
