iTunes AppStore recently achieved another milestone with 40000 apps existing for the iPhone/ iPod touch (though some of these apps are currently inactive, taking the effective number down).

Apple has also made it clear to its developers that all app submissions henceforth need to be compatible with the New iPhone OS 3.0 beta. While all the previous appstore apps for V2.x should be automatically compatible with the new OS, developers have been advised to check their apps for OS 3.0 compatibility.

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.

Existing apps in the App Store should already run on iPhone OS 3.0 without modification, but you should test your existing apps with 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.
