Apple (AAPL), Google (GOOG) and Research in Motion (RIMM) have reached something like a three-way stalemate in the battle for dominance of the U.S. smartphone market, according to Nielsen survey results scheduled for release Tuesday.
Smartphones are increasingly popular -- they now represent 37% of all U.S. mobile phones -- and smartphones running Google's Android operating system are the most popular of all. But Android's slice of the pie was no bigger in April than the last time Nielsen surveyed the field.
After having raced to the No. 1 spot in less than a year -- climbing from a 15% share in June 2010 to 37% in March 2011 -- Google held steady at 36% in the three month period from Feb. to April 2011.
