Updates stock information

SUNNYVALE, Calif. (

TheStreet

) -- Shares of

Palm

(PALM)

plunged in early trading Wednesday after a Credit Suisse analyst

downgraded

the smartphone maker.

Credit Suisse analyst Deepak Sitaraman warned that Palm's choice of

Sprint

(S) - Get Report

as the exclusive carrier for its new Pixi phone could hinder sales, and he lowered his rating from outperform to neutral.

Palm's stock slipped $1.05, or 7%, to $13.93 recently, despite the firm's

Pixi launch

Wednesday. Touted as a cheaper, lighter, version of the popular Pre, the Pixi will be available from Sprint in time for the holidays, although Palm did not announce pricing in its press release.

The phone specialist also lowered the price of its Pre phone to $149.99 with a two-year service agreement and after a $150 instant rebate and $100 mail-in rebate

In separate news, Sprint has confirmed that it will not offer customers a $100 credit to switch to the Pre from another carrier, contrary to a promotion on the company's Web site Tuesday. The offer was slated to run until Oct. 10, but

Sprint told

TheStreet.com

in an email that it was pulled.

The promotion on Sprint's Web site was a glitch caused by an error in Sprint's computer system, the

AP

reported.

Faced with stiff competition from

Apple's

(AAPL) - Get Report

iPhone, Palm is expected to make the Pre available to other carriers, including

Verizon

(VZ) - Get Report

and possibly

AT&T

(T) - Get Report

, next year.

Palm's stock slip ran contrary to the modest rally in tech shares Wednesday, which saw the

Nasdaq

gaining 0.8% recently.
