VoIP provider Skype plans to announce Tuesday that it will be working with SpinVox to provide its users with voice-to-SMS messaging in four languages.

This adds another option to Skype’s messaging notifications for both Windows and Mac, and it includes a free e-mail notification or a simple SMS notification when a contact leaves a message.

Converting the messages from voice to text won’t be cheap, however. Users will pay 25 cents per message, not including the standard Skype text message rate, and long voicemails could be spread out over as many as three messages. If the entire voicemail won’t fit into three texts, then the message will be cut off. Also, if the message is garbled or otherwise unconvertible–because of poor signal quality, for example–SpinVox and Skype will still charge you for the failed conversion effort.

Netflix is trying to locate the source of a series of glitches that some users of the company’s streaming service are blaming on Microsoft’s Silverlight video player.

Over the weekend, a steady stream of angry messages was posted to Netflix’s blog. The complaints range from choppy video, to audio that doesn’t sync with the picture, to grainy image quality.

The complaints began accumulating soon after the Web’s largest video-rental service switched to Microsoft’s Silverlight in November. The posts appear to have trickled in until last weekend, when a score of customers began reporting problems.

“The quality of the video looks like bad VHS,” wrote someone on the Netflix who identified themselves as Steve-O. “I use an Acer Netbook over my home network and the quality is poor. Also, I cannot even see the button to make the video full screen (using Acer One Netbook with Firefox browser). However, I imagine this will make the quality even worse. What a disaster.”

Netflix spokesman Steve Swasey said the company, which now has more than 10 million subscribers, has yet to pinpoint the cause of the malfunctions. He added that only a small percentage of customers have complained but that the company continues to look for a fix.

Swasey defended Silverlight. He said the company has received mostly kudos from customers after switching to the software last fall. A Microsoft spokeswoman declined to comment.

Mozilla on Wednesday released an update to the Firefox Web browser that its developers said fixes eight security issues found in Firefox 3.0.6, six of which were rated critical.

The most serious of the vulnerabilities fixed in Version 3.0.7 could allow attackers to run arbitrary code on a victim’s computer, Mozilla warned in security advisories Wednesday.

The six critical flaws affected the browser’s garbage collection–which monitors how Firefox modules use the computer’s memory–as well as the browser’s PNG libraries and in the layout and JavaScript engines.

Mozilla developers said they weren’t sure the layout and JavaScript flaws could be exploited.

Google Health has introduced a new feature that lets users share their online health records with designated doctors, friends, and family members.

Google said the move was in response to users’ concerns that care-givers and loved ones might not be up to date on all the details of a patient’s health situation, especially in the event of an emergency.

You may not have the latest $359 Kindle electronic book reader from Amazon.com, but if you own an iPhone or iPod Touch, a new application will let you access much of the same content on your Apple device.

In a bid to increase its slice of the e-book market, the Seattle-based online retailer rolled out a free program Wednesday that brings several of the Kindle’s functions to the iPod and iPhone’s smaller screen.

The program, which can be downloaded from Apple’s online application store, lets iPhone and iPod Touch users read the same electronic books that Kindle owners can buy on Amazon.com. As with the Kindle, the iPhone app lets users change the text size on the screen, and add bookmarks, notes and highlights.

The application does not connect to the Kindle store, however, so users must access the Web browser on their iPhone, iPod or computer to buy the content. Users cannot read magazines and newspapers on the Kindle application, either.

If you happen to have a Kindle and an iPhone, Amazon’s program will handily sync the two so you can keep your place in the same book on both devices.

The Kindle program isn’t the first e-book reader for the iPhone, but it marks the first time Kindle content is available on a cell phone - a move Amazon recently said it would be making, and something that rival Google Inc. is also doing.
