Apple has announced via their iOS Developer newsfeed that iOS apps that were developed and compiled for iOS 2.x will no longer be supported. Developers are being advised to re-build their apps in Xcode targeting iOS 3.x or later. Developers that continue to submit or have existing apps compiled against iOS 2.x will face removal of their app from the iTunes App Store.

In the same announcement Apple directed developers to their iOS 4 Readiness Checklist which includes a “wealth of technical resources” to help developers to take advantage of resources in iOS 4. Instructions and information about submitting iOS 4 apps to the App Store are also included.

Apple released iOS 4 as a free update for all iPhone 3G, iPhone 3GS, and the 2nd and 3rd generation iPod touch devices. iOS is fully compatible with all of these devices with the exception of the iPhone 3G and 2nd generation iPod touch which do not support all of iOS 4’s features. Apple has uncharacteristically offered iPod touch owners a free update, since in the past they had to pay approximately $10 for an OS update.
