With over 50 million users of iPhone and iPod touch in 81 countries around the world, it's more important than ever to make your app available in a user's language of choice. You can, and should, create localized versions of your app for each market you sell to. In iTunes Connect, you can customize your app's metadata, keywords and screenshots for each localized version.

We've expanded the list of languages available for localizing your app metadata, adding the following languages (listed along with the matching App Store territory):

• Brazilian Portuguese: Brazil App Store
• Korean: Korea App Store
• Portuguese: Portugal App Store
• Russian: Russia App Store
• Simplified Chinese: China App Store
• Swedish: Sweden App Store
  
  

If you have localized your apps, be sure to update the metadata language information for each of your localized versions whenever you update an app. In iTunes Connect, select Edit Application and click on the Localization tab; select the language from the pull-down menu.

You can add great new iPhone OS 3.x features to your application — In App Purchase, Push Notifications or the mail compose view — while maintaining compatibility with iPhone OS 2.x.

By using "weak linking" in your Xcode project, you can include frameworks you'll need for the newer features, and check for API availability when your application is running. This technique provides you with the broadest possible audience for your application. You can offer a game that runs great on iPhone OS 2.x, while adding the ability to buy new levels for users on iPhone OS 3.x. Or have a note-taking app that sends notes via the built-in Mail client on iPhone 2.x, and uses the Mail Composer Window within your application when it's running on iPhone 3.x. Just be sure to clearly identify any version-specific features of your app in your marketing description.

The MailComposer sample code demonstrates this technique of targeting older OS versions while building with newly released APIs, using the mail compose view (from the MessageUI framework) as an example.

For more information on weak linking in Xcode, see the SDK Compatibility Guide.
