Apple is turning 57.8 percent in gross profit off the iPhone, according to an estimate from Bernstein Research analyst Toni Sacconaghi. The figure puts Apple's profit well about that of other notable smartphone makers, such as HTC, Motorola and Nokia, and even RIM, which keeps about 42.6 percent of its BlackBerry sales revenue. The iPhone could eventually account for between 45 and 50 percent of Apple's revenue in FY2011, says Sacconaghi, up from about 30 percent in FY2009.
