Je viens de recevoir ce message de la part de l’équipe Android Market :

Hello,
We're writing to inform you about a couple changes to Android Market that require your attention.
First, we have added the ability to target applications by carrier in all countries.  For example, if you are showing your app in the United States, you can now choose among Sprint, T-Mobile, and Verizon Wireless.  If your apps are intended for users of specific carriers, please go to the Android Market developer website at http://market.android.com/publish (in the Publishing Options section under Locations) and target your applications to those carriers accordingly.
Second, Android Market will soon be available on devices with different screen sizes.  Until now, Android devices have only had "normal"-sized screens, e.g., HVGA (320x480).  The latest platform release, Android 1.6, expands support for upcoming devices that cover three different screen sizes:  small, normal, and large.  Please note that Android Market will allow apps built with the Android 1.5 SDK (or lower) to show only on normal- and large-screened devices.  Android Market will allow apps built with the Android 1.6 SDK to show on all three screen sizes.  Therefore, you will need to upgrade your app to Android 1.6 if you want it to also show on small screen devices that will launch in the coming weeks.  For complete details on Android's support for different screen sizes and the implications for your apps, we strongly recommend that you read the Android Developers Blogpost at http://android-developers.blogspot.com/2009/10/support-for-additional-screen.html.
Thanks, and we look forward to continue working with you on Android
Market.
Sincerely,

The Android Market Team
