In addition to the release of the Gold Master build to developers last night, here’s another sign that the public release of iOS 4.2 is imminent. Apple is calling for developers to test their apps with the GM build and submit them for approval so they can be ready when 4.2 is launched.
Here’s the wording on the email that went out to developers:
iOS 4.2 SDK GM seed and iOS 4.2 GM seed are now available from the iOS Dev Center. Build, test, and compile your apps with these new releases and submit them for review so they can be ready when iOS 4.2 is available to iPad, iPhone, and iPod touch users.
Learn how you can add exciting iOS 4.2 features to your apps including the capability to print directly from iPad, iPhone, and iPod touch. iPad apps can now take advantage of multitasking, Game Center, iAd, and more.
I imagine we will start seeing a flood of app updates for 4.2 compatibility very soon now.
