Global smartphone sales will grow another 46.5% this year to 688M units, predicts UBS, and thus account for 41% of the 1.69B mobile phones expected to be sold. However, revenue growth is expected to be just 21% - evidence of how much of the unit growth will come from cheap Android phones aimed at developing nations. UBS also sees 156.5M iPhone sales in Apple's (NASDAQ:AAPL) FY13 - more than twice the 72.3M sold in FY11.
