Google Inc. shares may surge 17 percent to $714, according to Lehman Brothers Holdings Inc., which said the operator of the world's most popular Internet search engine may introduce a mobile phone as early as February. Google's phone may be ``simple,'' ``low-priced'' and designed to run software over the Internet, Lehman analyst Douglas Anmuth wrote. His share-price estimate, which Anmuth today increased from $610, is the highest among 39 analysts covering Google that Bloomberg tracks. Mountain View, California-based Google advanced $6.88, or 1.1 percent, to $616.50 as of 8:11 a.m. in New York. The stock has gained 32 percent this year and yesterday surpassed $600 for the first time. Piper Jaffray & Co. analyst Gene Munster wrote in an Aug. 29 research report that Google may introduce software to run mobile phones by the end of this month to promote its e-mail and mapping services. Google spokeswoman Erin Fors said in response to Munster's note that the company doesn't comment on ``rumor or speculation.'' http://www.bloomberg.com/apps/news?pid=20601087&sid=aJOx43s6Sf3I&refer=home Great, the next mobile phone release !
