Apple has released a short statement that basically says, "It turned out to be harder to make the white iPhone 4 than we expected, so you'll have to wait a few more weeks to get your grubby little hands on it. And speaking of which, we expect you to keep it clean!" We suspect the real reason has to do with matching the exact shade of Stormtrooper White.

Apple tells Business Insider that the iPhone 4 video chat feature FaceTime uses voice minutes only to set up the initial connection. Once video chat begins, the voice connection is no longer used. While this makes sense - just as with iChat video, a peer-to-peer data connection is built for the connection - Apple didn't explain this so clearly at the iPhone 4 announcement or thereafter.

For yet another discussion of Apple's WWDC announcements, listen in as Adam and Tech Night Owl host Gene Steinberg talk about the top features in the iPhone 4, how FaceTime should integrate with iChat and Skype, and the change in AT&T's data plans, among much else.

TidBITS editor Glenn Fleishman explains in some depth at Ars Technica how so much Wi-Fi network congestion was in the air at the WWDC keynote. Based on discussions with two Wi-Fi experts, one of whom ran Apple's Mac networking hardware group for seven years, the iPhone 4 likely had a Wi-Fi driver bug, possibly triggered by the congestion.

The New York Times reports that a hacker group named Goatse Security has successfully exploited a hole in AT&T's Web site to access the email addresses of 114,000 iPad 3G users. AT&T has since patched the hole on its site, but the breach is a black eye for the company and could also harm the iPad's reputation, even though there's no indication that the problem was related directly to Apple.

MacNotables host Chuck Joiner has been confused about how EPUB and PDF compare, so Adam and Tonya tried to explain the pros and cons of each format in this MacNotables podcast. Adam also summarized the new features in Safari 5, and Chuck called upon listeners to vote in a poll to decide whether Adam or Tonya should get the new iPhone 4.

Remember the virtual world Second Life, which was much touted as the wave of the future some years ago? Well, it seems that the jokes about not needing to use Second Life in favor of your first life weren't just poking fun. According to TechCrunch, the user base has been shrinking and Second Life maker Linden Lab is laying off 30 percent of its workforce, giving all those employees a chance at a Second Career.

For those denied the pleasure of watching Steve Jobs unveil the iPhone 4 in person, Apple has posted a video of the 2010 WWDC keynote speech on its Web site. In addition to introducing the iPhone 4, Jobs and company also previewed iOS 4, an update to iBooks, the new video conferencing app FaceTime, and a hearty collection of app demos.

It seemed like all the other TidBITS staffers were getting them, so Joe Kissell and his wife wanted one too. On May 20, more than three weeks ahead of schedule, their long-awaited new product was delivered in Paris. Featuring a multi-touch surface, high-resolution video input, a fingerprint-resistant anti-glare finish, a 3D position sensor, wireless networking, and a (somewhat unreliable) sleep mode, this hardware-software combo has been providing them hours of entertainment and education. Frustratingly, it came without any documentation, and they've been unable to locate a mute button, but the developer promised that future upgrades will include face recognition, speech synthesis, and a power source that can last more than two hours between charges. The user interface will also be localized in French and English!

People who purchase an iPad Wi-Fi + 3G model before AT&T removes its unlimited data plan get to keep the option of paying for unlimited data. However, the iPad is back-ordered nearly everywhere, making it impossible to receive a new iPad before the June 7 switchover. In response, AT&T has stated that people who order the iPad by 11:59 PM on June 6 will be grandfathered in, even if they don't have the iPad in hand to activate the account.

Walmart has halved the price of the 16 GB iPhone 3GS to a mere $97. That's the lowest price you're likely to find in the United States, though most retailers will almost certainly follow suit once the next update to the iPhone arrives, probably within the next month. (Or so we suspect; the iPhone 3G dropped to $99 once the iPhone 3GS came out last year.) We recommend waiting for the next iPhone to ship before deciding whether you'd rather have the latest and greatest, or last year's model for less.

Kudos to our own Rich Mogull, whose TidBITS article about protecting your privacy from Facebook landed him a guest spot on the NPR radio show Science Friday with Ira Flatow (himself a TidBITS reader at one point). You can either listen to the audio of the show or read the transcript on NPR's Web site.

After 4 years and 66 ads, Apple's "Get a Mac" series of ads is no more. The last ads were produced in October 2009, and a comment by Justin "I'm a Mac" Long hinted that the campaign was done in an April 2010 interview. The URL to Apple's archive of the ads now redirects to the general "Why You'll Love a Mac" page. But if you're missing Long and costar John "I'm a PC" Hodgman, you can still watch all the ads at Adfreak.

The brouhaha surrounding privacy on Facebook continues to expand, with the New York Times producing a fascinating info-graphic that shows just how complex Facebook has made the topic, with 50 settings containing over 170 options. And the Facebook privacy policy? It's longer than the U.S. Constitution.

You know how many applications, when they crash, ask you for more information what you were doing at the time of the crash? Well, Garrett Murray spends a lot of time in Photoshop, and when it crashes, he sometimes feels the need to tell Adobe just what's on his mind at the time. The result is a hilarious collection of crash reports that make for great reading - one only hopes that the Photoshop engineers have enjoyed them as well.
