LAS VEGAS -- Palm ( PALM) finally got its much-awaited Treo 750 smartphone out the door, but that may be a small victory for the handheld device maker in an increasingly competitive market.

The Treo 750 phone arrives in Cingular Wireless retail stores and online Monday after a two-month delay that was largely responsible for the handheld-device maker's cutting earnings expectations during its second quarter.

The news from the annual Consumer Electronics Show here should be a relief to investors who were jolted when Palm slashed its earnings estimates on Nov. 27, resulting in an 8% drop in the company's share price.

Palm had blamed it on the failure to complete a certification for the phone by a wireless carrier.

Shares of Palm were up 12 cents or 0.8% to $14.81.

Getting the Treo 750, which runs Windows Mobile, into the hands of consumers should help Palm's third-quarter earnings, but it's unlikely to boost the company's long-term prospects.

Analysts expect to see revenue of $403.93 million in the third quarter and earnings of 12 cents a share.

Palm faces an increasingly difficult market for mobile devices. Nokia ( NOK) also on Monday introduced the N76 slim phone that combines a sleek design with complete multimedia capability that includes music and photos.

Nokia also introduced the N800 tablet device with access to RealNetworks' ( RNWK) Rhapsody music service and Skype ( EBAY) Internet calling.
