Nielsen in its US smartphone market share update called a rare three-way draw. The iPhone barely maintained its recent lead at the end of last year with 28 percent but was virtually even with Android and BlackBerry, both of which had 27 percent. The trend supported notions that Android was often cannibalizing BlackBerry sales as RIM had fallen over 10 percent from a year ago where Android grew from virtual non-existence in the same time frame.
