Apple issued a software update for OS X Mountain Lion Developer Preview 3 this evening. Apple released Developer Preview 3 to developers. The update brings the build number of Mountain Lion up to 12A193i (from 12A178q).

If you already have Mountain Lion Developer Preview 3 installed, choose Software Update from the Apple menu to download the update from the Mac App Store. Download Xcode 4.4 Developer Preview 4 from the Mac Dev Center to continue building apps for Mountain Lion Developer Preview 3 Update.

One change noted by 9to5Mac is the addition of a "Do Not Disturb" setting to Mountain Lion's Notifications Center:

Besides the Notification Center, Mountain Lion also borrows a number of other features from iOS, such as Reminders, Messages, and Game Center. Apple first previewed Mountain Lion back in February and promises deliver to customers in late summer 2012.

Following last week's leak of home buttons claimed to be for the next-generation iPhone, parts vendor SW-BOX.com has just posted information on a claimed iPhone 5 SIM card tray fresh from one of its parts suppliers.

The tray appears essentially identical to the SIM card tray found in the iPhone 4S and 4, and if the part is indeed legitimate it suggests that Apple may retain a similar flat-edged form factor for the forthcoming device. Such a design would be opposed to a tapered or rounded-edge design that would likely require a somewhat curved exterior surface for the tray or at least a thinner tray profile as was seen in earlier iPhone models such as the 3G and 3GS.

Apple has been pushing for its own "nano-SIM" standard, but has so far been unable to win approval as competitors have objected to the proposal and offered their own designs for a smaller next-generation SIM card. Unsurprisingly, it appears that a smaller nano-SIM design will not be ready in time to be included in the next-generation iPhone.

Apple is expected to introduce its next-generation iPhone later this year, with many observers suggesting that Apple will once again target the September-October timeframe for the launch. Many users have been hoping for a significant redesign following Apple's pattern of maintaining a similar form factor for two generations between major design overhauls, but part leaks that might reveal Apple's plans have yet to begin surfacing.

Update: As several observers have pointed out, the SIM card tray does have some subtle differences compared to the tray used in the iPhone 4S and 4, with a slight tapering of metal frame pieces and an extra metal shelf not seen in current trays. Consequently, the part certainly appears to not simply be an iPhone 4S SIM card tray, and while it could be a knockoff part, SW-BOX.com and its supplier seem to believe that it is genuine.

Apple has released a number of updates to several of its apps for the iPhone and iPad. The iLife apps, iPhoto, Garageband, and iMovie, all received minor updates, while Apple also pushed out bug fixes to the Cards greeting-card app, and to iTunes U.

None of the updates offer any significant new features -- the updates mostly offer "performance and stability improvements" or fix other bugs. All the updates can be obtained via the App Store app on the iPhone and iPad.

MacRumors is pleased to announce the third annual MacRumors Blood Drive, for the month of May 2012. We encourage forum members and site visitors to donate blood or platelets at any hospital or blood donation center in their city. We want to increase the number of life-saving donations by our online community for the benefit of people in their real-world communities. We also ask donors to post photos or stories in our Blood Drive thread. Saving a life is its own reward but accepting recognition as a donor helps spread the message to others. Please join us in showing the spirit of our community by donating blood or platelets this month and letting us know. Details are in the MacRumors 2012 Blood Drive thread.

Most blood drives are specific to a physical organization at a particular location. Ours is online and worldwide. You can help people in your city who are in need of life-saving blood and platelets in less than an hour of your time. If you are eligible to donate blood you can go to a hospital, community center, the Red Cross, or an independent donation center near you. If you are not eligible to donate yourself, please help the Blood Drive by encouraging other people to donate; see the Blood Drive thread for ideas.

Donated blood and platelets are needed every few seconds, all year, not just when calamities occur. They save the lives of people recovering from accidents, undergoing surgery, or struck by illness, including MacRumors forum members who have let us know that their lives were saved by donated blood. There's no gift more precious than the gift of life.

Specific donor eligibility requirements vary by country. For links and general information see our Blood and Platelet Donation Guide. You can also save lives by registering to donate your organs and tissue and by registering to be a bone marrow donor; see our Organ, Tissue, and Bone Marrow Donation Guide.

Apple's health, relief, and charity efforts over the years have included donations for 9/11 workers in 2001, the fundraising Songs for Sudan effort in 2004, (PRODUCT) RED participation since 2006, help for victims of the Haitian earthquake in 2010 and Japanese earthquake and tsunami in March 2011, and most recently a $50 million donation to Stanford University hospitals and a charitable donation matching program that are part of Apple's recent emphasis on corporate philanthropy.

The Travis County Commissioners Court has just given official approval for a package of tax incentives designed to secure Apple's commitment to expand its Austin, Texas campus and add over 3,600 new jobs at the site. The approval comes after development officials expressed concern last week that the deal was "in peril" as concerns over loopholes in the contract delayed approval by the county.

Prior to today's meeting of the Commissioners Court, the Austin American-Statesman reported on some of the tweaks to the contract, including language requiring Apple to pay the lowest-salaried 10% of its new employees at the site an average of $35,000 per year. Contractors, which may comprise up to 25% of the new hires, will be paid a minimum of $11 per hour.

Apple governmental affairs representative Jason Lundgaard was on hand for the session and answered several questions for the county commissioners.

Travis County is the final governmental entity to approve its portion of the total tax incentive plan, which is estimated to yield $35-36 million for Apple in exchange for adding the jobs and facilities. The State of Texas and the City of Austin previously approved their pieces of the deal.

Antivirus firm Symantec has published a new blog post examining how the Flashback malware affecting hundreds of thousand of Macs has been generating revenue for its authors by hijacking users' ad clicks. According to the report, the widespread nature of the infection means that malware authors could have been generating up to $10,000 per day from the scheme at its peak based on previous analysis of malware click redirection.

The Flashback ad-clicking component is loaded into Chrome, Firefox, and Safari where it can intercept all GET and POST requests from the browser. Flashback specifically targets search queries made on Google and, depending on the search query, may redirect users to another page of the attacker's choosing, where they receive revenue from the click . (Google never receives the intended ad click.)

Symantec's work on the ad-click hijacking aspect of Flashback comes after Russian firm Dr. Web, which was responsible for the initial publicity about the malware, published its own report examining some of the early data on infected computers seeking to connect to command-and-control servers.

The report looks at nearly 100,000 connections that came in on April 13, finding that close to two-thirds of the infected machines identified themselves as running Mac OS X Snow Leopard, which was the last version of OS X to ship with Java enabled by default. OS X Lion does not include Java by default, and thus was responsible for only 11% of infections seen during the survey period.

As noted by Computerworld, OS X Lion represents nearly 40% of OS X copies currently in use, suggesting that Apple's decision to remove Java from the default Lion install is indeed helping to limit infections on Apple's newest machines.

[W]hile Snow Leopard's and Leopard's infection rates are higher than their usage shares, the opposite's true of OS X 10.7, or Lion. The 2011 OS accounted for 39.6% of all copies of OS X used last month, yet represented only 11.2% of the Flashback-compromised Macs.

Dr. Web's data on OS kernel versions being reported from infected Macs also demonstrates that many Mac users do not keep their systems up-to-date, with roughly 25% of Snow Leopard and Lion systems seen in the survey reporting themselves as at least one version behind Apple's most recent updates (10.6.8 for Snow Leopard and 10.7.3 for Lion).

Research firm IDC today released its estimates of global mobile phone and smartphone shipments for the first quarter 2012, revealing that Apple set a record high in taking 8.8% of the overall mobile phone market. The performance just barely topped Apple's 8.7% share in the previous quarter, which was the launch quarter for the iPhone 4S.

Apple's year-over-year growth of 88% in an overall market which shrank by 1.5% enabled the iPhone maker to solidify its hold on third place in the overall mobile phone market behind Samsung and Nokia. Nokia had been the market leader for well over a decade, but Samsung surged into the lead for the first time during the quarter.

Looking at the narrower smartphone market, which now comprises 36% of the global mobile phone market, IDC pegs Apple in second place, with its 88% year-over-year growth easily topping the overall segment's growth of 42.5%. But Apple's growth was easily overshadowed by Samsung, which rode the strength of its portfolio of Android-based devices to year-over-year growth of 267% and the top spot in the smartphone rankings.

"The race between Apple and Samsung remained tight during the quarter, even as both companies posted growth in key areas," said Ramon Llamas, senior research analyst with IDC's Mobile Phone Technology and Trends program. "Apple launched its popular iPhone 4S in additional key markets, most notably in China, and Samsung experienced continued success from its Galaxy Note smartphone/tablet and other Galaxy smartphones. With other companies in the midst of major strategic transitions, the contest between Apple and Samsung will bear close observation as hotly-anticipated new models are launched."

Samsung's shipment numbers suffer from significant uncertainty, however, as the company no longer releases official data on its sales for competitive reasons. Consequently, analysts have had to resort to rough estimates for Samsung's numbers, and IDC believes that Samsung registered 42.2 million smartphone shipments to easily top Apple's publicly-released number of 35.1 million units.

Research firm Strategy Analytics last week offered a similar estimate of Samsung's shipments at 44.5 million units for the quarter, but IHS iSuppli painted a very different picture with its estimate of only 32 million smartphone units for Samsung, which would have left Apple atop the rankings for the quarter.

Apple today sent out an email encouraging Mac developers to sign up for the company's Developer ID program so that their apps can be properly signed ahead of the launch of OS X Mountain Lion later this year. Mountain Lion's Gatekeeper feature gives users the ability to set limits on app installation, with the new "Developer ID" program providing a middle ground of security by which developers can certify that they are the developer behind a given application package.

Should the developer be found to behave maliciously, Apple will be able to revoke the Developer ID associated with that developer, preventing applications signed with the ID from running and causing further harm to users.

The Mac App Store is the safest place for users to get software for their Mac, but we also want to protect users when they get applications from other places. Gatekeeper is a new feature in OS X Mountain Lion that helps protect users from downloading and installing malicious software. Signing your applications, plug-ins, and installer packages with a Developer ID certificate lets Gatekeeper verify that they are not known malware and have not been tampered with.

This marks the second such mass emailing to encourage adoption of Developer ID among the Mac developer community, as Apple sent out a similar mailing back in late February following its announcement of OS X Mountain Lion. The next major operating system is due for public launch in "late summer" and will undoubtedly be a featured topic at Apple's sold-out Worldwide Developers Conference in early June.

MacRumors has begun receiving reports that iTunes Match has started going live in several new countries today. So far we have heard from users in Austria, Greece, and Italy, with some users reporting that they have been required to agree to updated iTunes Store terms and conditions addressing the service while others have even been able to sign up for the service.

It remains unclear just how broad this latest round of debuts is, as Apple has yet to update its support document outlining availability of iTunes in the Cloud and iTunes Match, but signs of activity in various international iTunes Stores suggest that iTunes Match may also be going live in Bulgaria, Portugal, and Slovenia.

As part of the new rollout of Apple's paid iTunes Match service, users in these countries should also be receiving access to the free iTunes in the Cloud services for music and music video, which allow users to re-download purchased content any number of times to devices associated with their iTunes Store accounts.

Earlier this year, Apple began revealing more information about its Mastered for iTunes program, requesting that music professionals supply Apple with higher-quality recordings as source material for the compressed tracks made available for sale through the iTunes Store. The higher-quality source material, processed according to Apple's guidelines, is being requested to allow Apple to create better-sounding tracks in the 256 kbps AAC format used for the iTunes Store.

Ars Technica takes a thorough look at the Mastered for iTunes program and whether it truly does make a difference to consumers. While the whole article is an interesting read on some of the technical details of audio formats and mastering and the varying perspectives of several music industry professionals, Ars' conclusion is that the Mastered for iTunes program can make a difference in quality of iTunes Store music.

We enlisted Chicago Mastering Service engineers Jason Ward and Bob Weston to help us out, both of whom were somewhat skeptical that any knob tweaking could result in a better iTunes experience. We came away from the process learning that it absolutely is possible to improve the quality of compressed iTunes Plus tracks with a little bit of work, that Apple's improved compression process does result in a better sound, and that 24/96 files aren't a good format for consumers.

Ars worked with a number of audio engineers on test projects comparing various combinations of original 24-bit, 96 kHz master recordings, uncompressed WAV files ripped from CDs, standard iTunes Store tracks, and tracks created by applying Apple's Mastered for iTunes process to the master recordings. In one example, a standard iTunes Store track sounded "boxy" or "muffled" compared to the original CD master WAV file, but after processing through Mastered for iTunes tools, the resulting track sounded significantly better and more "alive" on a subjective basis.

Part of the difficulty in assessing sound quality comes from the emotional response involved in how sounds register to human ears. Some differences in sound quality can be quantified using various tools to analyze the waveforms generated by different audio files, but the ultimate measure of sound quality lies with the human ears receiving and interpreting the sounds.

Nevertheless, Apple markets the Mastered for iTunes program as providing a path for musicians and music professionals to have iTunes Store content more closely match "music as the artist and sound engineer intended", and more and more musicians are taking advantage of the program in attempting to improve the quality of their music available through the world's most popular music vendor.
