Emailing "Apple Releases Latest Beta of SDK 3.0"
You can now
obtain Beta 4 of the third version of the software development kit (SDK) for the iPhone and iPod touch. The SDK is what's allowed developers to create the thousands of applications—over a billion of which have been downloaded—that have helped to make Apple's mobile devices so successful. According to
TUAW, SDK 3.0 includes a number of new features, such as "over-the-air PIM synchronization sources (including Google and Yahoo in iTunes, per Joachim), copy and paste in Calculator, continued tethering support, and a basic UI for managing an iTunes store account." There's also a preliminary build of iTunes 8.2.
