* Nasdaq gains for third day
* Dow hurt by Coca-Cola's fall as corn futures jump
* Verizon and AT&T fall after brokerage downgrade

NEW YORK, June 16 (Reuters) - U.S. technology stocks rose on Monday for the third straight session, while blue-chip stocks declined slightly, as rising corn prices hurt beverage makers' shares and broker downgrades of leading telephone companies spurred some selling in that sector.
BlackBerry maker Research in Motion <RIMM.OQ> rose more than 6 percent after investors said that Nokia's new phone models would not pose a threat to RIM's dominance of the business market. It was among the Nasdaq's top-weighted gainers.
Weighing on blue chips were downgrades of Dow components Verizon Communications<VZ.N>, which fell 2.8 percent to $36.26, and AT&T <T.N>, which fell 1.5 percent to $36.14. UBS cut its ratings on the stocks to "neutral" from "buy," citing pressure from mobile competitors and the weak economy.
Fears that floods in the Midwest would drive up prices of soda ingredient corn syrup hit Pepsico Inc <PEP.N>, which fell 2.4 percent to $65.93, and Coca-Cola <KO.N>, which fell 2 percent to $54.34.
Corn prices have risen for eight straight days as floods cut back anticipated corn harvests in the Midwest. U.S. corn futures for July 2009 delivery <CN9> rose above $8 a bushel for the first time.
Nasdaq's gains were supported by the perception that big technology companies that cater to corporate customers have less exposure to the swings in consumer spending, said Mike McCarty, options strategist at Meridian Equity Partners, in New York.
The Dow Jones industrial average <
> was down 16.37 points, or 0.13 percent, at 12,290.98. The Standard & Poor's 500 Index <.SPX> was up 2.05 points, or 0.13 percent, at 1,361.74. The Nasdaq Composite Index < > was up 19.75 points, or 0.80 percent, at 2,474.25.Further supporting technology shares were perceptions that "they were beaten up ... so there is a little bottom fishing," said Todd Leone, head of listed trading at Cowen & Co. in New York.
The semiconductor index<.SOXX>, up 1.7 percent, was attracting particular interest since it was approaching its 200-moving day high, Leone added. Shares of Research in Motion gained 6.1 percent to $141.11 on the Nasdaq.
Declines in the broad market were offset by a rebound of 6 percent in the shares of investment bank Lehman Brothers Holdings Inc after its CEO Richard Fuld took responsibility for the company's first-ever quarterly loss, which reassured investors about the bank's stability. The quarterly loss of $2.8 billion matched Lehman's forecast. For details, see [
]Lehman shares rose 5.6 percent to $27.23.
Lehman's jump helped U.S. bank stocks, with the KBW bank index <.BKX> up 2 percent. Earlier in the day, Lehman's stock climbed as high as $28.21, a gain of 9.3 percent from its close on Friday on the New York Stock Exchange.
Another positive factor was the slight decline in U.S. oil futures prices after they hit a record high near $140 a barrel earlier in the day. On the New York Mercantile Exchange, U.S. crude oil for July delivery <CLc1> settled at $134.61 a barrel, down 25 cents. (Editing by Jan Paschal)
