Apple sold 6.1 million first generation iPhone units over five quarters.[286] Apple had achieved a 1.1% worldwide mobile phone share for the year 2008;[287] in the smartphone market it held an 8.2% share.[288] Sales in the fourth quarter of 2008 temporarily surpassed those of Research In Motion's (RIM) BlackBerry sales of 5.2 million units, which briefly made Apple the third largest mobile phone manufacturer by revenue, after Nokia and Samsung[289] (however, some of this income is deferred[290]). Numbers were lower in the first three quarters of 2009 until the fourth quarter surpassed sales of Q4 2008.[291] Recorded sales grew steadily thereafter, and by the end of fiscal year 2010, a total of 73.5 million iPhones had been sold.[292]
