Weighing at a whopping 1.2 gigabytes (GB), The iPhone Software Developer’s Kit (SDK) has been updated to Beta 8 (build 9M2199a)! Alongside the SDK, Apple has also seeded iTunes 7.7 beta to developers!

New Features in iTunes 7.7:

• MobileMe Support - “Use MobileMe to have push email, push calendars, push contacts, and bookmarks delivered over the air to your iPhone.”
• “Applications” in iTunes Sync with the option to sync “All” or “selected” applications.

Stay tuned for more details about the SDK and iTunes 7.7 beta!

iPhone developers should know, and probably already know, that Apple has released their second beta version of the SDK.

The second beta version of the iPhone SDK is now available and includes Interface Builder, a powerful tool that allows you to visually build your interface and makes creating a UI as simple as drag and drop.

We’ve also added new sample code and updated documentation to the rich set of resources available to you in the iPhone Dev Center.

Log in to the iPhone Dev Center today and download the new version of the iPhone SDK.

Thanks Manuel.

Apple has officially launched their iPhone Software Development Kit (SDK). Browse over to developer.apple.com/iphone/program to sign up —

Standard Program $99

The Standard Program is for developers who are creating free and commercial applications for iPhone and iPod touch.

Enterprise Program $299

The Enterprise Program is for developers who are creating proprietary, in-house applications for iPhone and iPod touch.

You’ll require an Intel-based Mac with Leopard and Xcode installed. Do note the SDK itself does not cost any money; however, getting your application approved for distribution under whatever program will set ya back.

Accessing the developer site seems a little iffy per the moment. Try again later should problems persist.

Thanks for the tip, Manuel.

Hey! Apparently the Apple iPhone SDK key has been leaked…

Read Erica Sadun’s report at TUAW, “…all iPhone applications must be properly signed for iTunes to process them and for the iPhone to load them, this key suggests that hackers are closer to creating compliant IPA application bundles for home-brew iTunes distribution.”
