With more than half its latest devices left on store shelves at the end of the third quarter, things may be getting out of hand for Palm as the manufacturer struggles to hold market share in the rapidly evolving telecom market.

After rolling out its latest operating system on its exclusive Nexus One smartphone in January, Google will now release Android 2.1 for a top competitor: the Motorola Droid, which is distributed by Verizon Wireless.

The over-the-air update will be available in batches of 250,000 beginning Thursday, March 18, Verizon Wireless announced. A blog dedicated to Android posted the official software update notice on Wednesday.

The fast-selling Droid is estimated to make up 15 percent of all Android smartphones sold.

Last year, Palm thought it had all the pieces for a turnaround in the market it pioneered: A new CEO known for making the iPod a household name, a sleek new smart phone called the Pre and fresh, intuitive operating software.

Instead, the company is in danger of going the way of its 1990s Palm Pilot, making it the latest innovator to learn that great technology and an accomplished leader don't guarantee success.

Having the latest and greatest Windows phones will no longer matter once Microsoft releases its Windows Phone 7 Series. Mobile-phone users running the latest Windows Mobile 6.5 operating system, made available in October, will have incremental upgrades but will need a new phone if they want to use the software giant's Windows Phone 7 mobile operating system.

Mobile-phone users with the latest Windows Mobile phones do not have the hardware needed to run the newest mobile operating system, according to Microsoft's Mobile Communication Business.

Hewlett-Packard unveiled its latest convertible tablet PC on Monday in what some are predicting will be a banner year for that class of devices. Geared toward small to midsize business owners, the EliteBook 2740p, which sells for $1,599, has multi-touch capabilities, runs Windows 7, and features Intel Core i7 or i5 processors, making it far faster than its predecessors.

The i7 processor runs at 2.66 GHz, while the i5 runs at 2.53 GHz. An alternative i5-520M runs at 2.40 GHz. The installed memory is 2GB or 4GB, but can be upgraded to 8GB.

T-Mobile USA, the fourth-largest U.S. wireless carrier, said Thursday it gained 371,000 new customers in the fourth quarter, reversing subscriber losses in the third quarter.

But the new subscribers were mainly low-paying ones who don't sign contracts, and T-Mobile USA's earnings and revenue fell from the same period a year earlier.

Google might figuratively be doing a backflip Thursday with news that AT&T will, for the first time, offer a mobile device based on the software and search giant's open-source Android mobile operating system. Appropriately, the device is Motorola's Backflip smartphone.

Some Verizon Wireless customers will soon have access to Skype, an Internet telephone service, the companies announced at the Mobile World Congress in Barcelona, Spain, on Tuesday. Skype, based in Luxembourg, allows people to use the service to make free video and voice calls. Users are also able to send instant messages and other files.

Verizon data customers will be able to make and receive unlimited Skype-to-Skype voice calls, according to the companies. Users will also be able to make international calls using Skype Out, a competitive service.

With key mobile platforms and their application communities rapidly moving forward, a group of wireless carriers and device makers have decided to simplify. On Monday, two dozen of the largest telecom companies announced plans to create an open platform called the Wholesale Applications Community (WAC).

The world's largest wireless carriers, including the four largest in the U.S., announced Monday that they are combining forces to make it easier for software developers to write applications that will run on as many phones as possible.

The "Wholesale Applications Community" is an attempt to retake the initiative from phone makers like Apple Inc., Nokia Corp. and Research in Motion Ltd., which have applications stores of their own. Google Inc. is also building a significant store for its Android software.
