Shares of Synchronoss Technologies ( SNCR) were among technology's winners Wednesday, jumping 13% after the software provider said that Cingular selected its software platform for use in Apple's ( AAPL) new iPhone product.

"This is significant for Synchronoss because it not only represents an additional driver to our Cingular-related revenue, but also because it is a major step forward in our efforts to move our ActivationNow platform up the stack," Synchronoss said.

Synchronoss reiterated its 2007 adjusted earnings forecast of 44 cents to 48 cents a share. The company predicts revenue of $99 million to $100 million. Analysts polled by Thomson First Call project earnings of 44 cents a share and revenue of $99.9 million. Shares were trading up $1.98 to $16.75.

Perficient ( PRFT) rose 8% after the information technology consulting firm boosted its fourth-quarter revenue estimate. The company expects to report revenue of $48.4 million to $49.6 million, up from an earlier forecast of $42.4 million to $45.1 million. Analysts, on average, project revenue of $44.6 million. Shares of Perficient were trading at $18.72, up $1.37.

Shares of Ramtron ( RMTR) tumbled 15% after the chipmaker cut its fourth-quarter revenue projection. The company now estimates revenue of $9.1 million to $9.2 million, below its earlier forecast of $10.2 million to $11.2 million. Analysts anticipated revenue of $11.4 million. Ramtron attributed the shortfall to an earthquake in Taiwan and severe weather in Colorado, which resulted in product shipment delays. Shares were trading down 53 cents to $2.90.

Adaptec ( ADPT) fell 8% after the computer-hardware maker cut its third-quarter earnings and revenue forecast. The company expects to report an adjusted loss of 2 cents to 5 cents a share for the recently ended quarter. Adaptec's previous guidance called for results ranging from a loss of a penny a share to a profit of a penny a share. The company lowered its revenue estimate to $60 million to $61 million from $70 million to $74 million. Wall Street expected a profit of 1 cent a share and revenue of $72.6 million.

The company blamed the shortfall on a "significant decrease" in revenue from IBM ( IBM), which had accounted for about 30% of Adaptec's total revenue over the past several quarters. Adaptec shares were down 37 cents to $4.13.

Shares of LeCroy ( LCRY) slumped 11% after the company warned that second-quarter results would disappoint investors. The company, a maker of electronic testing equipment, expects an adjusted operating profit of $500,000 to $1 million for the quarter ended Dec. 31. The company estimates revenue of about $38 million. Analysts forecast earnings of 27 cents a share and revenue of $42.6 million.

"Although we began the second quarter with strong order activity, the month of December was slower than expected, particularly in the Asia-Pacific area," LeCroy said. Shares were trading down $1.20 to $10.23.

Other technology movers included Apple, up $3.18 to $95.75; Sun Microsystems ( SUNW), up 17 cents to $5.90; Intel ( INTC), up 21 cents to $21.24; Microsoft ( MSFT), down 31 cents to $29.65; Cisco Systems ( CSCO), up 2 cents to $28.49; and Level 3 Communications ( LVLT), down 3 cents to $6.
