Apple mandates iPhone OS 3.0 for apps, warns of 2.x removals

Apple has emailed registered iPhone developers to inform them all app submissions will be tested on iPhone OS 3.0, starting today. In the email provided to iLounge, Apple states, “Beginning today, all submissions to the App Store will be reviewed on the latest beta of iPhone OS 3.0. If your app submission is not compatible with iPhone OS 3.0, it will not be approved.” The email continues, “[e]xisting apps in the App Store should already run on iPhone OS 3.0 without modification, but you should test your existing apps the iPhone OS 3.0 to ensure there are no compatibility issues. After iPhone OS 3.0 becomes available to customers, any app that is incompatible with iPhone OS 3.0 may be removed from the App Store.” Apple is expected to release iPhone OS 3.0 this summer.
